Here are the key parts of a seed:
- Seed coat: A protective outer covering that protects the embryo and stores food. Seed coats come in many colors, textures, and thicknesses depending on the plant.
- Embryo: The tiny new plant inside the seed. It contains a miniature stem, leaves, and sometimes a root tip.
- Cotyledons: The first pair of leaves inside the embryo. Cotyledons contain stored food for the embryo to use as it begins to grow into a seedling.
- Endosperm: A tissue inside some seeds that contains food reserves like carbohydrates, proteins, and fats. The endosperm provides nourishment for the embryo as
The document summarizes the parts of a flower and their roles in reproduction. It explains that flowers contain reproductive organs and are made up of four main parts: sepals, petals, stamens, and pistils. The sepals protect the bud, petals attract pollinators, stamens produce pollen as the male part, and pistils receive pollen and contain ovaries to produce seeds as the female part. Pollination occurs through pollen transfer from the stamen to the pistil by wind, insects, or other animals. Fertilization happens when pollen grains fuse with egg cells in the ovary, developing into seeds and eventually fruit to protect and disperse the seeds.
The document classifies plants into two main categories: flowering plants and non-flowering plants. Non-flowering plants include mosses and ferns. Mosses do not have true roots or vascular tissues, reproduce via spores, and prefer damp environments. Ferns have roots, leaves, underground stems and vascular tissues, reproduce via spore-producing organs on their leaves, and prefer damp shady places. Flowering plants are further divided into gymnosperms like pine trees, which have needle-shaped leaves and bear naked seeds in cones, and angiosperms which have true flowers and fruits containing seeds. Angiosperms include monocots and dicots, distinguished by whether they have one or two seed leaves and
1) The document discusses the parts of a plant and their functions. Roots take in water and nutrients, stems move water and nutrients through the plant, and leaves use sunlight to make food.
2) Flowers produce fruits containing seeds. Seeds come in many shapes and sizes and are scattered by wind, water, animals or planting.
3) When conditions are right, a seed will germinate and a seedling will grow from the seed. The seedling develops roots, stem and leaves and the process repeats as it produces seeds of its own.
The document discusses the main parts and functions of plants. It explains that most plants have three main parts: roots, stems, and leaves. The roots hold the plant in the soil and absorb water and minerals. The stem carries water and minerals from the roots to the leaves, supports the plant, and can be thick like a tree trunk, thin like a bush, or soft like grass. The leaves make food for the plant using sunlight, air, and water. Flowers are the reproductive part where seeds form, and fruit protects the seeds so new plants can grow.
Plants are living things that require air, water, soil, and sunlight to survive. They produce their own food through the process of photosynthesis, where leaves absorb sunlight and use it to convert carbon dioxide and water into oxygen and sugars. The main parts of a plant are roots, which take in water and nutrients; stems, which transport water and raise leaves and flowers; leaves, which produce food for the plant; and flowers, which produce seeds. Photosynthesis occurs in leaves and uses chlorophyll to power the process of turning carbon dioxide, water, and sunlight into oxygen and food. Plants are essential as they produce food and oxygen, and help clean the air and soil.
The document discusses the parts of a plant and how plants grow from seeds. It notes that roots take in water and nutrients from the soil, stems hold up the plant and move water and nutrients, and leaves use sunlight, air, water and nutrients to make food. Flowers make fruits containing seeds. Seeds are scattered by planting, animals, water and wind and can germinate into seedlings when they have sunlight, air, water and nutrients.
There are two main types of roots: tap roots and fibrous roots. Tap roots grow vertically downward from the seed and are long and tapered, such as those in carrots. Fibrous roots spread out horizontally when grass and cereal seeds germinate to absorb water near the soil surface. Some plant roots also function to store food underground, like carrots, or provide support to help climbing plants stand, such as black pepper.
The document discusses the basic parts of a plant, including roots that take in water and minerals to support the plant, a stem that moves water through the plant and supports it above ground, leaves that take in air and light to produce food for the plant through photosynthesis, and flowers that produce seeds for new plants. The objectives are to identify the basic plant parts and explain the functions of roots, leaves, stems, and flowers.

The document discusses the main parts of a plant including seeds, roots, stems, leaves and flowers. It describes the function of each part, with seeds growing into new plants, roots absorbing water and minerals, stems carrying water and sugar, leaves producing food, and flowers making fruit or being pretty blossoms. It also lists examples of edible plant parts like roots, stems, leaves, flowers, fruits and seeds.
This document discusses different types of plant adaptations. It describes terrestrial plants that grow in various environments like plains, mountains, deserts, areas with heavy rainfall, swampy areas, and coastal regions. It also discusses aquatic plants like floating plants, fixed plants, and underwater plants. Insectivorous plants that trap insects are described along with non-green plants. Examples are provided for each category. The document concludes by listing some useful plants and their products.
Basic presentation of the parts of a plant and of the life cycle of plants. Pitched at about the 2nd, 3rd or 4th grade level. Lots of descriptive pictures and diagrams.
The document discusses the main parts of a plant and their functions. It identifies the roots, stem, leaves, flowers, seeds, and fruits as the basic plant parts. The roots absorb water and nutrients from the soil and anchor the plant. The stem transports water and nutrients between the roots and other parts, and supports the plant. The leaves use sunlight to photosynthesize and produce food for the plant. Flowers hold the seeds and fruits contain seeds which can grow into new plants.
This document summarizes key information about plant structures and classifications. It begins by identifying the four main characteristics shared by all plants: they perform photosynthesis, have a cuticle layer, cell walls, and alternation of generations. It then describes the four major groups of plants as nonvascular plants, vascular plants, seed plants, and flowering plants. The document provides examples and explains the structures, functions, and importance of roots, stems, leaves, and flowers. It also distinguishes between gymnosperms and angiosperms.
Male and female gametes from plants unite during sexual reproduction to form a zygote, which develops into a new plant body. Sexually reproduced offspring have two parents and thus exhibit more variation than asexually reproduced offspring that have a single parent. Pollination involves the transfer of pollen grains containing male gametes from the anther to the stigma. It can occur through biotic vectors like insects or abiotically via wind or water. Self-pollination involves pollen transfer within a flower or between flowers on the same plant, while cross-pollination transfers pollen between plants. Asexual reproduction requires only one parent and can occur via vegetative propagation using plant structures like stems, leaves, and roots
This document discusses the different parts of plants and their functions, as well as the process of photosynthesis. It notes that plants have leaves, stems, roots, and flowers, with each part playing an important role - leaves make food through photosynthesis, stems transport water and nutrients, roots absorb water and nutrients from the soil, and flowers produce seeds. The document then examines the structure and function of leaves in more detail, and classifies plants based on their structure, root and stem types, whether they produce seeds or spores, and whether they are edible.
This document compares the key differences between monocots and dicots. It begins by explaining that flowering plants are divided into two classes: monocots and dicots. The main differences discussed are that monocots have vascular bundles that are scattered in the stem cross-section, while dicots have vascular bundles arranged in a ring. Examples of monocots include palms, grasses, orchids and onions, while dicots include oaks, roses, mustards, cacti and sunflowers. Images are also provided showing the different vascular bundle arrangements in a monocot and dicot plant.
Flowering plants have evolved various adaptations for seed dispersal to spread seeds far from the parent plant. The main methods of seed dispersal are by wind, by animals, by water, and by explosion. Seeds dispersed by wind are light with structures like hairs that aid wind transport. Seeds dispersed by animals pass through digestive tracts unharmed and are deposited far from the parent in feces. Seeds dispersed by water may survive ocean currents, while explosive plant pods forcibly eject seeds from the parent.
The document summarizes key characteristics of the four main groups in the plant kingdom - bryophytes, pteridophytes, conifers, and angiosperms. Bryophytes include mosses and are small non-vascular plants that reproduce using spores and live in damp environments. Pteridophytes are vascular plants like ferns that can grow larger than bryophytes due to possessing tissues like xylem and phloem. Conifers are gymnosperms that bear naked seeds in cones, while angiosperms are flowering plants that produce fruits enclosing seeds.
The document discusses flowers, their structures and functions. It defines flowers as compressed shoots bearing floral leaves that are the reproductive structures of plants. The main external parts of a flower are described as sepals, petals, stamens and pistils. Variations in flower structures and types of inflorescences are covered. The development of pollen grains and ovules is summarized, as are the processes of pollination, fertilization and fruit/seed formation.
The document discusses the main plant parts and their functions, including roots that take in water and nutrients from the soil, a stem that transports water and food throughout the plant and holds it upright, leaves that perform photosynthesis using carbon dioxide, sunlight and water to produce oxygen and energy for the plant, and flowers that attract pollinators to help the plant reproduce and produce seeds. It emphasizes that plants are important to habitats by providing beauty, food, shelter and more.
Pollination is the transfer of pollen grains from the stamen to the stigma of a flower. There are two main types of pollination: cross-pollination which is the transfer of pollen between two different plants, and self-pollination which is the transfer of pollen within the same flower or plant. Pollination can be carried out by insects, wind or water, with the main agents being insects like bees and butterflies, or the wind. Insect-pollinated flowers tend to be large, brightly colored with scents to attract insects, while wind-pollinated flowers are smaller and dull colored without scents.

How Are Flowers Useful to Us?
Flowers are not just beautiful to look at,
but they also serve a vital role in our ecosystem.
Flowers help our ecosystem flourish and attract a plethora of life to the area and facilitate the expansion of our environment. If flowers are cut down or destroyed before pollination can occur, that particular species has a high chance of dying off in that area. In addition, local wildlife will also vanish in that area since they would have no food. Flowers help keep the ecosystem growing and provide new plant life, as well as help sustain local insects and birds.

The parts of a plant and their functionsIrfanfahrizza
Plants have five basic parts - leaves, stems, roots, flowers, and fruit - that each serve important functions. Leaves produce oxygen through photosynthesis and release water through transpiration. Stems transport water and nutrients throughout the plant via vessels. Roots take in water and minerals from the soil using root hairs. Flowers function to sexually reproduce the plant species to ensure its continuation. Fruits contain seeds and can either have one seed like mangoes or multiple seeds like guavas.
Plants produce flowers which have male and female organs. The male organ, or stamen, contains pollen. The female organ, or carpel, contains the stigma, style and ovary. Seeds are formed when pollen from the stamen fertilizes the carpel. Flowers have specific parts - the stigma receives pollen, the style supports the stigma, the ovary holds the ovules that become seeds, the anther produces pollen, and the filament supports the anther.
There are 5 main parts to a plant: roots, stems, leaves, flowers, and seeds. Roots take in water and food from the soil and keep the plant in place. Stems stand the plant up and act as an elevator to transport water and food. Leaves breathe in air and take in sunlight. Flowers attract pollinators to make seeds. Seeds contain a small plant and are how plants reproduce.
Plants require water, air, sunlight and nutrients to grow and thrive. Their roots take in water and nutrients from the soil, while their stems carry food and water throughout the plant. Leaves collect sunlight to fuel photosynthesis, and flowers attract insects to aid in pollination and reproduction.
Plants originated from green algae in the oceans and have since colonized all environments on Earth through adaptations. They are divided into two main groups - plants without seeds like mosses and ferns, and plants with seeds including gymnosperms like conifers and angiosperms. Plants are multicellular autotrophs that produce their own food through photosynthesis, where chloroplasts in leaves use chlorophyll, water, carbon dioxide and sunlight to produce oxygen and glucose. Sexual reproduction in seed plants involves pollination transferring pollen between male and female parts, leading to fertilization and seed formation in fruits.
The document discusses the plant system and its main components. It describes how plants have root systems that absorb water and nutrients from the soil. Stems transport water and nutrients between the roots and leaves, and also provide structure and support. Leaves use photosynthesis to produce food for the plant by using energy from sunlight, carbon dioxide from the air, and water from the roots. Flowers produce seeds and fruits protect and disperse the seeds. Photosynthesis overall provides food for plants and oxygen for other living things.
The document discusses key concepts about plants for grade 1 science, including that plants are living things that cannot move, produce their own food through photosynthesis, have roots that absorb water and nutrients, stems that transport water and nutrients, and leaves that are the site of photosynthesis. It also discusses pollination, respiration, transpiration, seeds, and the roles of flowers, fruits, and stems. An upcoming grade 1 science app is described that will teach these concepts through a game with 20 levels covering the four science streams.

Plants are multicellular autotrophs that produce their own food through photosynthesis, where chloroplasts in leaves use chlorophyll, water, carbon dioxide and sunlight to produce oxygen and glucose. Sexual reproduction in seed plants involves pollination transferring pollen between male and female parts, leading to fertilization and seed formation in fruits.
The document discusses the plant system and its main components. It describes how plants have root systems that absorb water and nutrients from the soil. Stems transport water and nutrients between the roots and leaves, and also provide structure and support. Leaves use photosynthesis to produce food for the plant by using energy from sunlight, carbon dioxide from the air, and water from the roots. Flowers produce seeds and fruits protect and disperse the seeds. Photosynthesis overall provides food for plants and oxygen for other living things.
The document discusses key concepts about plants for grade 1 science, including that plants are living things that cannot move, produce their own food through photosynthesis, have roots that absorb water and nutrients, stems that transport water and nutrients, and leaves that are the site of photosynthesis. It also discusses pollination, respiration, transpiration, seeds, and the roles of flowers, fruits, and stems. An upcoming grade 1 science app is described that will teach these concepts through a game with 20 levels covering the four science streams.
This document summarizes key aspects of plant structure and function. It describes how plants are grouped based on characteristics like whether they are vascular or nonvascular. It explains the main parts of vascular plants - roots, stems, and leaves - and their various structures and functions. The document also details photosynthesis, the process by which plants use sunlight, carbon dioxide, and water to produce oxygen and energy in the form of sugar. It compares how plants, animals, and decomposers obtain energy and survive.
Plants have four main characteristics and are divided into four groups. They are the producers that use photosynthesis to make their own food from sunlight, carbon dioxide, and water. Plants are classified as either nonvascular, which lack transport tissues, or vascular, which have transport tissues to move water and nutrients. Vascular plants are further divided into seedless plants and seed plants. Seed plants form seeds after fertilization which contain a young plant, stored food, and a protective seed coat. They are classified as gymnosperms, which have naked seeds, or angiosperms, which produce flowers and fruits.
The document discusses the life cycle of a plant from seed to pollination in several stages:
1) A seed starts as a hard coated structure that germinates with sunlight and water, developing into a plant.
2) Roots form and push into the ground while a stem grows upwards, forming leaves to photosynthesize.
3) Flowers are produced to attract pollinators like insects and animals.
4) Pollination occurs when pollen is transferred between flowers by pollinators or wind, allowing seeds to form and the cycle to repeat.
Plants have four main organ systems: roots, stems, leaves, and reproductive structures. Roots absorb water and minerals from the soil and anchor the plant. Stems provide structure, support, and transport of water and nutrients. Leaves use photosynthesis to produce food for the plant and exchange gases. Reproductive structures such as flowers and fruits help plants reproduce by producing seeds.
This document discusses the parts and lifecycle of flowering plants. It identifies the main plant parts as roots, stems, leaves and flowers. It describes the function of each part, with roots anchoring the plant, stems providing support, leaves producing food, and flowers making seeds and attracting pollinators. The lifecycle of a flowering plant is also summarized in four stages - from seed, to sprouting, developing leaves and buds, and finally growing flowers and completing the cycle by making new seeds.
This document discusses the parts of plants and their functions. It explains that roots absorb water and nutrients, stems transport water and provide structure, leaves produce food through photosynthesis and transpire water, and flowers aid reproduction through developing fruits and seeds. The document emphasizes that plants are an important source of food for humans, providing edible roots, stems, leaves, flowers, fruits, and seeds. It also describes the process of seed germination through a suggested activity.
Plants have specialized tissues and structures that fall into two main categories - the shoot system and root system. The shoot system is made up of stems, leaves, flowers, and fruits. Stems support the plant and transport nutrients and water. Leaves capture sunlight through photosynthesis to produce food. Flowers attract pollinators and produce seeds. Fruits protect seeds and aid in their dispersal. The root system anchors the plant, absorbs water and nutrients from the soil, and transports them to the shoot system.

This is helpfull for students, Photographers and other requirements. This is all in one pack with photography and some of the details about plants which is useful for any kind of projects or in the occasion of world photography day and its more convenient and simpler in design.
The document discusses the structures and functions of plant organs and tissues, dividing plants into two main groups - bryophytes which lack specialized tissues for transport, and tracheophytes which have vascular tissues like xylem and phloem. Key plant organs like roots, stems, leaves, and reproductive structures are described. The transport systems allow tracheophytes to grow larger by moving water, nutrients, and food throughout the plant.
Flowering plants have four main parts: roots, stems, leaves, and flowers. Roots take in water and nutrients from the soil. Leaves use photosynthesis to produce food from sunlight. Flowers produce pollen and attract pollinators to help the plant reproduce by making seeds. Seeds can sprout and grow into new plants that will also produce roots, stems, leaves, and flowers.
PLANT STRUCTURE, CLASSIFICATION, GROWTH AND DEVELOPMENT.Andrea Gancero
Plants are important as they produce oxygen, food, building materials and more. They obtain energy through photosynthesis using sunlight, carbon dioxide and water. Plants are classified based on characteristics like habitat and whether they are woody or non-woody. A plant's growth is influenced by internal factors like hormones and external environmental factors like temperature, light and climate. Farmers must understand these factors to successfully grow crops.
The document summarizes the main parts of a plant and their functions. It explains that leaves perform photosynthesis to produce food, flowers produce seeds for reproduction, stems support the plant and transport water and nutrients, roots absorb water and minerals from the soil, and seeds contain embryos that supply energy and materials for new plant growth. It also states that plants are living organisms that grow, need nutrients, reproduce, are made of cells, and react to their environment.
Plants undergo three basic living processes: relation, nutrition, and reproduction. Nutrition involves roots taking in minerals and water to create raw sap, which travels through the plant's xylem vessels to the leaves. In the leaves, photosynthesis transforms raw sap into food by using sunlight, water, carbon dioxide, and minerals. Reproduction can occur sexually through pollination and the creation of fruits and seeds, or asexually by plant parts like stolons, tubers, bulbs, and rhizomes creating new plants without fruits or seeds.
The document provides an overview of botany basics, including plant life cycles, internal and external plant parts, and key differences between monocots and dicots. It discusses the main internal parts of plants including cells, tissues, and meristems. For external parts, it describes roots, stems, leaves, and reproductive structures. Roots are described in more detail, covering their internal zones, epidermis, cortex, vascular tissue, root hairs, and mycorrhizal relationships. The chapter distinguishes between annual, biennial, and perennial plant life cycles.
The document summarizes the main parts and functions of plants. It describes how roots absorb water and nutrients from the soil and anchor the plant. Stems transport water and minerals between roots and leaves, provide structure, and in young plants can photosynthesize. Leaves perform photosynthesis to produce food, exchange gases, and release water through transpiration. Flowers have four main parts - calyx, corolla, androecium, and gynoecium - which are involved in reproduction.
1. The document outlines the main parts and functions of plants. It discusses how plants are made up of root and shoot systems, with each part playing specialized roles. The root system anchors the plant underground and absorbs water and nutrients, while the shoot system grows above ground and carries out processes like photosynthesis, reproduction, and transporting water and nutrients.
2. Key parts of the shoot system are then described in more detail. The stem provides structure and transports fluids within the plant. Leaves perform photosynthesis and gas exchange. Flowers contain the reproductive organs and produce seeds. Fruits develop from flowers to protect and disperse mature seeds.
This document provides an overview of the key structures and functions of plants. It discusses the main tissue systems - dermal, vascular and ground tissues - that make up plant bodies and allow them to transport water and nutrients. Roots are described as having important functions of nutrient/water uptake and transport. Stems are discussed as providing structure, support and a transport system between roots and leaves. Leaves are highlighted as the main photosynthetic organs. The document also covers plant diversity and types of plant reproduction including seeds and their protective structures.
Plants have several organs that work together to carry out important functions like making food, transporting water and nutrients, and reproduction. Leaves use photosynthesis to produce sugar from sunlight, carbon dioxide and water. Stems support leaves and transport materials between plant parts. Roots take in water and minerals from the soil. Flowers contain male and female reproductive parts and enable pollination and fertilization to produce seeds, allowing the plant to reproduce.
This document discusses animal and plant adaptations that enable survival in different environments. It provides examples of structural, behavioral and physical adaptations in both animals and plants. It explains how adaptations like camouflage, mimicry and body coverings help animals survive and find food, shelter and protect themselves from predators and weather. Adaptations in plants like roots, leaves, dormancy and response to seasonal changes are also covered. Examples of adaptations in polar bears, walruses, giraffes and pelicans are given to illustrate how structures help animals survive.
Seedlings grow from seeds and contain the food needed for the young plant to grow. Flowers produce seeds which start the next generation. Pollination occurs when pollen is transferred between flowers by insects, animals, wind or water, allowing seeds to form. Non-flowering plants grow directly from seeds into trees or shrubs without producing flowers.
In this module, students learn about volume and extending their understanding of two-dimensional figures. They explore volume through cubic units and develop the volume formula for right rectangular prisms. Later, students examine two-dimensional figures and work with area involving fractional side lengths. The module builds on students' previous work with fractions and decimals and prepares them for exploring the coordinate plane in the next module.

This document provides information about the major organ systems in the human body and compares them to similar structures in plants. It discusses the circulatory system including the heart, blood vessels, and their functions of transporting nutrients, oxygen, waste throughout the body. The respiratory system including the lungs and their role of absorbing oxygen and removing carbon dioxide is described. Other systems covered include the skeletal, muscular, nervous, digestive, excretory, reproductive, and integumentary systems. The key similarities and differences between plant and animal organ systems are highlighted such as plants making their own food while animals must consume other organisms for nutrients.
The document describes the major organs of the human body and their functions. It discusses how the heart pumps blood, the lungs provide oxygen and remove carbon dioxide, and the stomach breaks down food. It also explains that the liver makes bile to help digest food and fight disease, while the kidneys filter waste from the blood and the intestines further break down and absorb nutrients from food.
The document discusses forces and motion. It defines a force as a push or pull that can cause an object to start, stop or change direction of motion. There are different types of forces including pushes/pulls, friction, magnetism and gravity. Friction opposes motion while gravity causes objects to fall. The motion of an object depends on the balanced or unbalanced forces acting upon it.
Forces can be either balanced or unbalanced. Balanced forces are equal opposing forces that do not cause a change in an object's motion. Unbalanced forces are unequal opposing forces that produce a change in an object's motion. A net force is the sum of all forces acting on an object. An object will accelerate in the direction of a net force.
There are six basic forms of energy: mechanical, electrical, heat, light, sound, and chemical energy. Mechanical energy includes potential energy, which is stored energy due to an object's position, and kinetic energy, which is energy of motion. Potential energy can be gravitational or elastic. Electrical energy comes from the movement of charged particles and can be transformed into other forms of energy. Heat energy is how hot or cold an object is and is transferred between objects. Light and sound energies are forms of wave energy that travel away from their sources. Chemical energy is stored energy due to molecular arrangements.
This document discusses the big idea of forces and changes in motion. It explains that a force is a push or pull that causes an object to change its motion. Gravity and magnetic forces are examples of natural forces. Isaac Newton published three laws of motion explaining how forces cause motion. The document then defines different types of forces like gravity, friction, and magnetic forces. It also explains how forces can change an object's speed, direction, and velocity according to Newton's second law of motion. Mass affects how much force is needed to change an object's motion.
25 p.10.4 transformation of electrical energy ppt (2) (1)Christine Snyder
Electrical energy can be transformed or changed into heat, light, and sound energy, as well as the energy of motion. When an electrical current passes through a light bulb, the electrical energy is transformed into light energy, causing the bulb to glow. In a toaster, electrical energy is converted into heat energy, which warms the bread. An electric fan transforms electrical energy into kinetic energy as the blades spin and move air around a room. Electrical devices are also able to produce sound through the transformation of electrical energy. The law of conservation of energy states that energy cannot be created or destroyed, only changed from one form to another.
This document discusses weather and climate concepts for 5th grade students. It defines weather as the condition of the atmosphere at a particular place and time, noting that weather can change rapidly. It describes how weather is determined by air temperature, barometric pressure, humidity, wind speed and direction, and precipitation. It explains how these factors are measured using tools like thermometers, barometers, hygrometers, wind vanes, and rain gauges. The document also discusses different types of clouds and precipitation and how geographical features can impact climate zones.

Creativity for Innovation and SpeechmakingMattVassar1
Tapping into the creative side of your brain to come up with truly innovative approaches. These strategies are based on original research from Stanford University lecturer Matt Vassar, where he discusses how you can use them to come up with truly innovative solutions, regardless of whether you're using to come up with a creative and memorable angle for a business pitch--or if you're coming up with business or technical innovations.
Artificial Intelligence (AI) has revolutionized the creation of images and videos, enabling the generation of highly realistic and imaginative visual content. Utilizing advanced techniques like Generative Adversarial Networks (GANs) and neural style transfer, AI can transform simple sketches into detailed artwork or blend various styles into unique visual masterpieces. GANs, in particular, function by pitting two neural networks against each other, resulting in the production of remarkably lifelike images. AI's ability to analyze and learn from vast datasets allows it to create visuals that not only mimic human creativity but also push the boundaries of artistic expression, making it a powerful tool in digital media and entertainment industries.

8. Sunlight—Plants get energy from the Sun. Chlorophyll found in
plant leaves uses sunlight to change water, minerals, and
carbon dioxide into food. This process is called photosynthesis.
Water—Plants must have water because it helps carry nutrients from the
soil to the plant's roots. Water is a part of plant cells and is a main ingredient for
photosynthesis.
Minerals—Plants need soil because they use it to get water, nutrients, and minerals.
Air—Plants also get nutrients from the air. During photosynthesis, plants take in carbon
dioxide from the air and release oxygen.
Space—Plants also need space to grow. If there are too many plants for the amount of
sunlight, soil, minerals, or space, some of the plants will not survive
9. Roots—Roots anchor the plant in the soil, take in
water from the soil, and take in nutrients from the
soil.
Leaves—Leaves are where photosynthesis mainly
takes place. Leaves take in carbon dioxide from the air
and absorb sunlight energy. Both of these things are
needed in order for the plant to make food through
photosynthesis. Leaves exchange gases with the
atmosphere through holes called stoma.
Stems—Stems provide structure for the plant and
allow water and nutrients to travel throughout the
plant. The stems of some plants can also help the
plant to reproduce. If the stem is planted in the
ground correctly, a new plant will grow

47. The Parts of a Flower
• Sepals protect the bud until
it opens.
• Petals attract insects.
• Stamens make pollen.
• Pistil contain the ovary
which contains the ovules
(eggs).
• When fertilized, ovules
grow into fruits which
contain seeds.
50. Parts of a flower
• The male part of the flower is the stamen which
include the anther and filament.
– The anther produces pollen grains.
• The female parts of the flower is the pistil which
includes the stigma, style, ovary and ovule.
58. Pollination
• Pollination is the transfer of pollen grains
from the anther to the stigma of a flower.
– The pollen grains can be transferred within the
same flower.

59. Pollination
• Pollen grains can be transferred by wind, insects,
bats and birds.
– The pollen grains can also be transferred from one
flower to another.
60. What is Pollination?
Gizmos: Flower Pollination
Pollination is the act of transferring pollen grains from
the male anther of the stamen to the female stigma.
Pollen lands on a female pistil, sperm cells move
down to the ovary, fertilizing the egg cells.
Fertilization combines DNA.
The result is a seed with a tiny plant inside.
The ovary grows into a fruit to protect the seeds.
63. Pollinators
Animals, wind, and water can all
help in the transfer of pollen.
We call animals or insects that
transfer pollen from plant to plant
"pollinators ".
The flower type, shape, color, odor,
nectar, and structure vary by the
type of pollinator that visits them.
64. Wind Pollination
Some flowers, such as grasses, do not
have brightly colored petals and nectar
to attract insects. These flowers are
pollinated by the wind.
65. Flowering plants use:
• the wind
• insects
• bats
• birds
• mammals
to transfer pollen from the stamen (male)
part of the flower to the stigma (female)
part of the flower.
66. Check Point
• What is pollination?
• How do flowering plants depend on other
living things in order to reproduce?
• Why are young plants like but not identical to
their parents?
67. Fertilization
• After pollination a flower
becomes fertilized.
• Fertilization is when the
female egg cell and the male
sperm cell combine.
• A tube containing the male
sperm cell grows down the
style to reach the ovules in
the ovary.
• Inside each ovule is an egg
cell.

72. Seed Dispersal
• Seeds can be easily carried by
wind, water, or animals.
• Some fruits can be eaten by
animals and the seeds are
then dispersed.
73. How do seeds get dispersed
from a plant into the ground?
• Some seeds are hidden in the ground by animals such as
squirrels as a winter store.
• Some seeds have hooks on them and cling to fur or clothes.
74. How do birds and animals
help seed dispersal?
Birds and animals eat the
fruits and excrete the seeds
away from the parent plant.
75. Ways Seeds are Carried Away from a Plant
• Animal-carried
• Animal-consumed
• Water-borne
• Wind-borne
• Propelled

Which part of the seed is not shown in the
photograph?
95. Observing a Seed
1. Observe the outside of a dry bean seed with a hand
lens. Draw it and write down four or more properties
including length and width.
2. Get a wet bean seed to observe. Draw it and write
down four or more properties including length and
width.
3. Why is the wet seed larger?
4. Split it open and observe its parts. Draw and label its
inside including the seed coat, cotyledon, and
embryo.
97. Seeds are scattered by planting, wind, water,
and animals.
When the small plant inside begins to grow, the seed
germinates.
The young plant that grows from a seed is the
seedling.
Remember…
98. What are some plants that produce seeds?
corn
pine tree sunflower
99. DO ALL PLANTS MAKE SEEDS TO
REPRODUCE?
Ferns and Mosses do not grow
seeds. Instead they produce
spores.
104. What are some plants that
produce spores?
ferns
mosses
105. Ferns DO NOT have seeds. Instead, they reproduce
with spores. A spore is a tiny part of a fern that can
grow into a new plant. Spores DO NOT have a food
supply for the young plant like seeds do.
106. Characteristics of Ferns
• Ferns are plants that reproduce through spores
which are found on the underside of leaves.
• Ferns can be found in damp and shady places.
• They have roots, feathery leaves, and
underground stems.
108. This fern has big leaves divided into many smaller
parts. It has “dots” on them. The “dots” on the
underside of the leaves are cases where spores
grow. Spore cases have spores inside them.
109. Characteristics of Mosses
• Mosses are some of the simplest
plants with simple stems and leaves.
• Mosses have spores which can be
found inside a capsule.
• The spores are dispersed by the wind.
118. Characteristics of Cone-bearing
Plants
• They reproduce with cones.
• They are tall evergreen trees with
roots and a woody stem.
• They have needle-shaped leaves.
• They are usually found in dry places.
120. WHAT ARE CONIFERS?
Conifers are non-flowering
plants that grow seeds just as
most plants do. Their seeds are
found in CONES which makes
them unique…
122. REVIEW Questions

123. REVIEW Questions
1. Explain how the conifer plant on the
left reproduces.
Answer: Conifer plants like this pine tree
reproduce by forming seeds inside of
pine cones, which are spread throughout
the forest by the wind and/or animals.
124. 2. What is the main difference between the way a fern
and an orange tree reproduce?
Answer: An orange tree is a type of flowering plant that
reproduces by means of seeds.
A fern is a nonflowering plant that reproduces by means
of spores.

126. Plants
Respond to
Stimuli
SC.3.L.14.2 Investigate and
describe how plants respond to
stimuli (heat, water, gravity),
such as the way plants stems
grow toward light and their
roots grow downward in
response to gravity.
127. ESSENTIAL QUESTION
• How Do Plants Respond To Different Changes
In Their Environment?
• Think about what plant part is responding and
how that change is allowing the plant to adapt
and survive.
128. What is Stimuli?
• Stimuli is when a plant responds to its environment.
(Adaptations to its surroundings.)
• When plants change how they grow or move it is
called Tropism – growth or movement
• Examples are
• Plants roots grow towards water (hydrotropism)
• Stems grows towards light (phototropism)
• A plant grows vertically and roots grow down to the
pull of gravity (gravitropism or also referred to as
geotropism.
• Plant responding to heat thermotropism
129. Response to Stimuli
As they grow, plants respond to conditions around them.
Light
Gravity
Water

131. What are the plants doing in each of
these pictures??
132. Light
• Some plant parts grow, or turn towards the sun.
Plant parts include leaves, stems, flowers
• A plant can take in more light if it faced the sun.
• Leaves must take in light to make food for the
plant.
• Turning towards the sun helps a plant make the
food it needs.
Why do leave and stems of plants often grow
upward?
136. What are the plants
doing in these
pictures? What is it
called?
It’s gravitropism or geotropism!
137. Gravity
• Gravity causes roots to grow
downward.
– Growing downward helps roots reach
water and nutrients in soil.
– It helps roots to support the plant. (Roots
help keep water and wind from carrying
the plant way).
• Stems grow upward away from the pull
of gravity.
– It helps the leaves face the sun and take in
light.
139. Plants Respond to Gravity Too
On its side or upside down. Plants use the
force of gravity to get right side up.
Office of Academics - Department of Science
145. Heat- Temperature
• In places with cold winters, many flowers
bloom in spring.
• Some flowers can bloom any time it gets
warm enough.
• Some fruits will not get ripe in cool
weather.
• Many plants stop growing new leaves or
flowers when it gets cold.
– Helps them to live without water or enough
sunlight.
146. Some flowers open during the day and
close at night.
• Dandelion
• Water Lily
• Lotus Flower
147. Plants need Heat Energy
In order for seeds to sprout (germinate) they need heat
energy and water. Too much or too little heat will not allow
the seed to germinate. Once they have sprouted, they need
LIGHT and water more so than HEAT so that photosynthesis
can then occur in the leaves.
Plants react to
cold by folding
up to save
Heat Energy.
Different plants
grow at different
temperatures.
Some plants will
only grow under
the right
temperature
conditions.
148. Heat
• Plants do have natural systems that respond to
heat problems. Transpiration is a mechanism in
plants to cool themselves by “pumping” water
out through the leaves for a kind of swamp-
cooler effect.
• If temperatures increase chemicals (proteins)
inside the plant surround other “proteins” so
the plant can keep its shape.

156. How do plants respond to different
changes in their environment?
Light Gravity Heat
157. YOU DO: Choose one plant response and
write a letter as a consumer. You are
benefiting because the plant has adapted to
the “stress” in its environment (either due to
heat, gravity, light, or water) The plant is at
some point a food source that will enable you
to survive.
Are you the herbivore, omnivore,
carnivore, or even a decomposer?

Benchmark:
Compare and contrast the major stages in the life
cycles of Florida plants and animals, such as those
that undergo incomplete and complete
metamorphosis, and flowering and non-flowering
seed-bearing plants.
Essential Question:
What similarities and differences exist in the
life cycles of Florida plants and animals?
162. Life Cycles
All living things grow and change in
predictable patterns called life cycles. A
life cycle is defined as the complete
succession of changes undergone by an
organism during its life. A new cycle occurs
when an identical set of changes is begun.
165. Life Cycle of Plants
Most plants go through a similar life cycle.
Follow the life cycle of a lima bean plant.

169. Plants
• Plants come from seeds. Each seed contains a tiny plant waiting for the
right conditions to germinate, or start to grow. Seeds wait to germinate
until three needs are met: water, correct temperature (warmth), and a
good location (such as in soil). During its early stages of growth, the
seedling relies upon the food supplies stored with it in the seed until it is
large enough for its own leaves to begin making food through
photosynthesis. The seedling's roots push down into the soil to anchor the
new plant and to absorb water and minerals from the soil. And its stem
with new leaves pushes up toward the light. The germination stage ends
when a shoot emerges from the soil. But the plant is not done growing.
It's just started. Plants need water, warmth, nutrients from the soil, and
light to continue to grow.

174. seed
Seed—Seeds are reproductive structures that some
plants produce. Each seed contains a tiny baby
plant and the food the plant will need to break out
of the seed, grow up through the soil, and grow its
first leaves.
187. What is photosynthesis?
• Process plants use to make their own food
• Plants’ leaves contain chlorophyll
• Chlorophyll (green color) makes
photosynthesis possible
189. What is needed for
photosynthesis to occur?
• Light is needed for photosynthesis to occur.
The plant’s leaves use the light to make a
sugar called glucose.
190. Plants make their own food
in their leaves using four
ingredients:
1. Sunlight from the sun
2. Water
3. Carbon dioxide (CO2)
4. Chlorophyll from the
leaves
How does Photosynthesis work?
191. The chlorophyll in
the leaves captures
the sunlight’s
energy and along
with the water and
carbon dioxide
plants produce a
food called sugar
and release oxygen.
How does Photosynthesis work?
192. Photosynthesis
• Photosynthesis is the process of making
food by plants
• The essential ingredients in making this
food are sunlight, the chlorophyll that is
present in green plants, water and carbon
dioxide in the air.
193. How it All Works Together?
In Photosynthesis,
a plant produces
plant sugar and
Oxygen using light
energy. The
leaves use water
and nutrients
transported by the
Roots and through
the Stem, and the
Carbon Dioxide
from the Leaves
and changes them
using Light as
energy.
194.
195.
196. Water is taken in through the roots of the
plant and transported to the leaves by
the xylem (tubes that carry water) in the
stems.
197. The Carbon dioxide
animals breathe out
goes into the leaves
through the tiny pores
called stomata. It then
spreads to the cells
that contain
chlorophyll in the
inside layer of the leaf.
202. Sunlight is used to break down the water in the
plant into oxygen which the plant gives off and
we use to breathe.
203. The hydrogen is then used with the carbon
dioxide to create the food for the plants and
ultimately food for animals as well.
204.
205. Why do plants need glucose?
• Glucose is the food for the plant. It gives
the plant energy to grow.
206. How much glucose does a plant
make?
• Plants make enough glucose to be used during
the night and on cloudy days when they don’t
get sunlight. The extra glucose is stored in the
plant’s leaves and other parts.
207. Photosynthesis is necessary not just for plants to
make food for themselves, but for animals,
including us eventually.
210. Animals including humans make the CO2
(carbon dioxide) plants need.
They (the plants) make the O2 (oxygen)
and food we need.
211. How does photosynthesis help us?
• During the process of photosynthesis,
oxygen is produced. We use this oxygen to
breathe.
212.
213. How does photosynthesis work?
Draw an illustration with captions to explain how plants
make their own food through Photosynthesis.
Vocabulary to include:
carbon dioxide (CO₂) chlorophyll leaves
oxygen sunlight sugar
water (H₂O)
