The document summarizes key concepts about the world of plants including plant reproduction, pollination, fertilization, seed dispersal, and asexual reproduction. It discusses the life cycle and structure of plants and flowers. It also covers commercial plant propagation techniques like cuttings and grafting which allow for consistent production of desired plant varieties.
1. Most plants grow from seeds, which are protected by a seed coat.
2. If a seed gets water and warmth, the plant inside will start to grow, with roots growing down into the soil and a stem and leaves growing up.
3. As the plant matures, it will produce flowers that make fruits containing new seeds, allowing the cycle to continue as those seeds may grow into new plants.
The document discusses different animal habitats including deserts, forests, jungles, savannas, oceans, and polar regions. It describes the key features of each habitat such as climate, vegetation, seasons, and some example animal species. Different habitats provide animals with the water, food, and shelter they need to survive.
The document discusses a classroom experiment where students planted sunflower seeds in soil, paper towels, and various containers to observe plant growth over 4 days. The seeds began to sprout stems and leaves, and the students watched as the sunflowers and roots continued to grow with regular watering. They explored how sunflower seeds develop into plants when provided with the necessary requirements of soil, water, sun, and air.
This document outlines the key parts of a plant and what plants need to grow. It discusses the six main parts of a plant: roots, stem, leaves, flowers, seeds, and fruit. It also explains that plants need four things to grow: air, water, soil, and light. The document provides pictures and descriptions of each plant part and growth requirement.
Living things, including animals and plants, need certain things to survive. Animals require food, water, shelter, and air to stay alive. Plants need nutrients from soil, water, air, space to grow, and sunlight. Both animals and plants need these basic necessities to provide energy and allow biological functions like breathing.
Plants need water, light, nutrients, and air to grow. Water is necessary for seed germination and plant growth. Plants use sunlight to photosynthesize and make their own food. Nutrients from the soil provide minerals for healthy growth. Light, air, and water allow plants to photosynthesize and produce food to support growth and health.
Leaves are essential for plants to produce food through photosynthesis. They take in water and carbon dioxide, using sunlight to make sugar. Water travels through pipes in the plant from the roots. Leaves also help protect plants by being poisonous, sharp, or tough. Roots hold the plant in the ground and take in water and nutrients, while stems transport water and minerals between the roots and leaves and also store food. Different plant structures like cactus stems and potato stems have adapted to help plants survive.

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 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.
Insects make up half of all living things on Earth, with over a million known species and many more still undiscovered. All insects have six legs, an exoskeleton, and three body parts - a head, thorax, and abdomen. While not all insects have wings or the same mouthparts, they all breathe through openings in their abdomen and have compound eyes with thousands of lenses providing wide vision.
This document summarizes three main types of plant habitats: terrestrial, aerial, and aquatic. Terrestrial plants live on land and have stiff stems and roots to support their growth and access to sunlight, water, and nutrients from the soil. Aerial plants live attached to other surfaces above the ground and obtain moisture and nutrients from the air. Aquatic plants live in water and have adapted leaves, stems, and roots suited to their water environment, such as leaves that float or roots that absorb oxygen.
The document discusses the life cycles of humans, animals, and flowering plants. It provides examples of life cycles such as butterflies, mosquitoes, frogs, cats, and flowering plants. For humans, it outlines the stages of foetus, baby, childhood, adolescence, adulthood, and old age. It also explains the reproductive parts of flowers and processes of pollination, fertilization, seed production, dispersal, and germination that are common to many plant life cycles.
This document discusses the characteristics and needs of living things. It states that all living organisms grow, reproduce, and respond to their environment. It contrasts living things with non-living things, which do not grow, reproduce or respond. The document also outlines the basic needs of living things, including water, space, food, and gases. It provides examples to illustrate how plants and animals obtain these necessities.
This document discusses different types of animals and what they eat. It explains that cows, zebras and rabbits are herbivores that eat plants. Lions, tigers and crocodiles are carnivores that eat other animals. Bears, pigs, monkeys and people are omnivores that eat both plants and other animals.
The document discusses various types of invertebrate animals. It describes their characteristics such as lacking backbones, having exoskeletons, tentacles, shells, legs or segments. Some examples provided include sponges, jellyfish, worms, snails, insects and arachnids such as spiders. Invertebrates make up 97% of the animal kingdom and live in a variety of environments on land and in water.
The document classifies plants into different types based on their size, stem properties, and where branches appear. Herbs are small plants less than 1m with green tender stems and few branches. Shrubs are medium sized from 1-3m with thin hard stems and branches near the base. Trees are the tallest over 3m with thick hard brown stems and branches in the upper part. Creepers have weak stems and spread along the ground, while climbers climb with support.
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.
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

The document summarizes weather, climate, and adaptations of animals. It discusses how weather and climate impact daily life and influence the clothes worn, modes of transport used, and types of food grown. It also explains that all living organisms are adapted to survive in the climatic conditions of their natural habitat. Different climate zones around the world such as polar, tropical rainforest, and desert regions are described. The adaptations of animals living in these regions like polar bears, penguins, monkeys, and frogs are outlined to help them cope with temperature extremes and precipitation levels.
This document discusses different types of animals including their habitats, diets, and characteristics. It notes that animals can live on land, in trees, or in water. It describes herbivores that eat plants, carnivores that eat meat and other animals, and omnivores that eat both plants and meat. Specific animal examples are provided for each dietary category. The document also provides lists of different types of mammals and birds and calls out some of their defining traits.
Plants are living things that grow like humans, ranging in size from very short to very tall, and some have beautiful leaves and flowers. The document suggests activities for children ages 4 and up, such as going with parents to spot different plant types, collecting flowers to make a collection, and growing a plant.
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 life cycle of a plant begins with a seed, which germinates into a seedling. The seedling grows into an adult plant that produces flowers. Flowers have male and female parts that are involved in reproduction and enable the plant to produce seeds. Some plants reproduce via cones instead of flowers. Seeds are dispersed by wind, water, or animals eating fruit and depositing seeds elsewhere, allowing new plants to grow and repeat the cycle.
The document describes different types of animals including mammals, birds, fish, reptiles, and amphibians. It defines their key characteristics such as having fur or feathers, breathing methods, birthing young, and whether they lay eggs. Examples are provided of animals that would be classified as mammals, birds, fish, and amphibians based on these distinguishing traits. The purpose is to teach how to classify animals based on their physical features, means of reproduction, and locomotion.
Different animals have different life cycles, with changes in size and shape as they develop from young to adult. Some young animals resemble their parents while others look very different, undergoing changes until they take on the appearance of the adult form of their species.
Soil is the layer of loose material on Earth's land surface and is made up of particles of rock, air, water, and humus. Soil is organized into layers with topsoil at the surface containing the most humus and nutrients for plant growth, subsoil below it containing some humus and rock particles, and bedrock forming the bottom layer underneath. Soil types vary depending on the amounts of sand, silt, and clay particles in them, with loam being an ideal mixture supporting plant growth.

The document outlines the process of sexual reproduction in flowering plants, including the structure and function of floral parts, pollination, fertilization, seed formation, dispersal, dormancy, and germination. Key points include that pollen grains produce male gametes, the embryo sac produces an egg cell and polar nuclei, double fertilization occurs, seeds vary in structure depending on whether they are endospermic or non-endospermic, and seeds require specific conditions like water and oxygen to successfully germinate.
Seed plants reproduce through seeds, which contain an embryo and stored food inside protective seed coats. Seeds come in many shapes and sizes depending on the plant. Pine trees reproduce through male cones that produce pollen and larger female cones that receive pollen and produce seeds. Flowers also help in reproduction, with male stamen producing pollen and female pistils receiving pollen. Pollination occurs when pollen is transferred, allowing fertilization and the production of seeds inside fruits. For seeds to germinate and grow into new plants, they need favorable conditions like water, warmth and light.
Seed plants reproduce through seeds, which contain embryos that allow new plants to grow. Seeds have three main parts - a seed coat for protection, stored food, and an embryo which is the baby plant. Seeds are dispersed in various ways, such as on the surface of pine cones or inside fruits. For seeds to germinate, they need the right conditions of heat, water, and warm temperatures to allow the embryo inside to grow into a new seedling.
Flowers have different parts that allow plants to reproduce. Sepals protect the bud, petals attract pollinators, and reproductive parts include carpels and stamens. Carpels contain ovaries, styles and stigmas while stamens contain filaments and anthers. Pollination occurs when pollen is transferred, allowing fertilization to take place in the ovary and seeds to develop. Seeds are then dispersed by various methods like wind, water, or animals so new plants can grow in different locations away from the parent plant and not be overcrowded. During germination, seeds need water and warmth to grow into new plants, completing the life cycle of flowering plants.

Seeds contain stored energy to help young plants grow. They reproduce plants and can travel via wind, water, or animals. Seeds have three main parts - a seed coat, cotyledons which provide food, and a small embryo plant. Monocots have one cotyledon while dicots have two. Germination involves water soaking the seed coat, the coat splitting, and the root and shoot emerging to become a new plant using energy from the cotyledons.
This document provides information and activities for a science lesson on asexual and sexual reproduction in plants for 9-10 year olds. It includes:
- Key definitions of asexual reproduction using bulbs, tubers, runners and plantlets, and sexual reproduction using seeds.
- Suggested activities such as investigating seeds in different fruits, comparing seed size and number, and observing plant growth from cuttings.
- A glossary of terms and an example of how a student may present their findings comparing seeds from different fruits.
Vegetative propagation allows plants to reproduce rapidly without seeds or pollination by producing genetically identical offspring through structures like bulbs, corms, rhizomes and tubers. These structures store food to support new growth. Sexual reproduction involves meiosis and fusion of male and female gametes during pollination and fertilization to produce offspring with genetic variation, aiding species survival. Angiosperms typically reproduce sexually through flowers containing stamens that produce pollen and pistils containing ovules. Successful seed germination requires water, oxygen, and warm temperatures as shown through an experiment with mung bean seeds.
Plants are vital for life on Earth. They convert sunlight into food through photosynthesis, produce oxygen, regulate climate, provide habitats for other organisms, and give us food, materials and medicines. Plants live in almost every habitat and maintain the balance of gases in the atmosphere. They come in a huge variety and have complex structures adapted for reproduction, growth and survival.

2. Leaves take in carbon dioxide and water, and through photosynthesis, produce oxygen and sugars to fuel plant growth. Specialized structures called stomata allow for gas exchange.
3. Plants can reproduce both sexually, through pollination and fertilization to produce seeds, and asexually through methods like bulbs, rhizomes, cuttings, and tissue culture.
How planta feos and How Seeds travel (1).pptrv8v542trb
ย
This document discusses how plants grow from seeds and how seeds are able to travel. It explains that seeds contain embryos that allow new plants to grow when the seed germinates in soil that provides water, space, sunlight, and nutrients. Flowers produce seeds that can be dispersed in various ways, such as sticking to animal fur or blowing in the wind, in order to create new plants. The document outlines the stages of a seed germinating and a plant growing, from a seed being planted and sprouting roots, to a full-grown plant that can reproduce by making its own seeds.
This document provides an overview of seed collecting and starting, including the basics of flower and seed anatomy, harvesting seeds, cleaning and storing seeds, breaking dormancy through stratification and scarification, germinating seeds using paper towels or outdoor winter sowing, and tips on timing and care for seedlings. The agenda covers plant reproduction, identifying seeds and seed parts, techniques for collecting, cleaning and storing seeds, and methods for stratifying, scarifying and germinating seeds indoors or outdoors over winter.
This document summarizes key parts of flowering plants and their sexual reproduction. It describes the structures of flowers, including sepals, petals, stamens and carpels. It explains pollination and how pollen tubes carry pollen to the ovary for fertilization. The document contrasts insect-pollinated and wind-pollinated flowers. It also summarizes the process of fertilization, seed and fruit formation, dispersal of seeds, and germination of seeds.
NEW STANDARDS 6th grade Plants1: classification & processesRobin Seamon
ย
The document provides an overview of plant classification and processes. It divides plants into two main categories: nonvascular and vascular plants. Nonvascular plants include mosses and lichens. Vascular plants are further divided into seedless plants like ferns and seed plants like gymnosperms and angiosperms. It describes the characteristics and examples of these different types of plants. The document also covers plant structures, functions, and processes like photosynthesis, transpiration, and the plant life cycle.
Plants reproduce both sexually and asexually. Sexual reproduction involves a male and female parent producing offspring that are genetically different, while asexual reproduction involves one parent producing offspring that are genetically identical clones. There are advantages to each type of reproduction depending on the environment and situation. Asexual reproduction is simpler and requires less energy, making it preferable when colonizing new areas or in harsh environments where sexual reproduction may not be successful.
1. Double fertilization involves the union of two sperm cells with an egg and polar nuclei in flowering plants. One sperm fertilizes the egg to form the zygote, and the other fertilizes the polar nuclei to form the endosperm.
2. The zygote will develop into the embryo, and the endosperm provides nutrition for the developing seed. This double fertilization is unique to flowering plants.
Plant Reproduction and Propagation Techniques Infocards for 4th grade showc...Mary Van Dyke
ย
This document provides information on plant reproduction and propagation techniques. It discusses the parts of dicot and monocot seeds, plant sexual reproduction through flowers, vegetative reproduction through tubers, bulbs, grafting, and conifer cones. Examples are given for dicot beans and lima beans, monocot corn, parts of flowers, coconut seeds, fern and moss lifecycles, potato tubers, grafting fruit trees, bulb anatomy, and conifer cones. Credits and links are provided for further information.
This document discusses life cycles and reproduction in plants and animals. It covers:
- The stages in plant and animal life cycles, including germination, growth, reproduction and dispersal.
- How plants reproduce through pollination and fertilization to form seeds and fruits.
- The stages in a human life cycle from baby to adult.
- Differences between human and animal development and parenting responsibilities.
- The seven main life processes all living things require.
The document discusses several trees and plants that were used by Native Americans in Washington State. It describes how camas bulbs were an important food source and were harvested annually. Sword ferns were used for mattresses, baking pits, and their spores were used as ointment. Broad-leaved cattails provided food that could be eaten like corn or boiled like potatoes. Sitka Spruce bark and roots were used for basketry, hats, and rope. The Pacific Yew provided wood for tools like bows, paddles, and clubs. Douglas Fir was used for salmon spears and its bark was boiled for healing and camouflage. Vine Maple twigs were used for weaving and
1. The document discusses the evolution of early land plants and their adaptation to living on land through the development of adaptations like mechanical strength, light catching surfaces, and systems for water transport and nutrient absorption.
2. It describes the alternation of generations life cycle, where plants alternate between a haploid gametophyte generation and diploid sporophyte generation.
3. Key examples of early land plants discussed include mosses, which produce sporophytes on top of gametophyte bodies, and ferns, which demonstrate a free-living gametophyte phase and a dominant sporophyte phase.
Gymnosperms are seed plants that produce naked seeds, not enclosed in fruits. They include trees like giant sequoias and conifers like pine trees, as well as shrubs. Gymnosperms are some of the oldest land plants, with cycads dating back 175 million years. While most gymnosperms are trees with needle-like or scale-like leaves, some like ginkos and welwitschia are also shrubs. Conifers are the most common gymnosperms seen today, reproducing through cones that hold either pollen-producing male cones or ovule-containing female cones.
Gymnosperms are seed plants that reproduce via naked seeds not enclosed in an ovary. There are five phyla of extant seed plants, four of which are gymnosperms. Coniferophyta, or conifers, is one of the gymnosperm phyla and includes trees like pines, hemlocks and redwoods. Conifers bear their naked seeds on modified leaves called sporophylls and have adapted traits like wood to support their large size, with some being among the largest and oldest living organisms.
The document discusses the reproductive structures and processes of angiosperms or flowering plants. It describes the structure of flowers and how they are adapted for pollination by wind, animals, or water. Pollen grains contain male gametes that are transferred during pollination to another flower of the same species. After pollination, fertilization occurs where the male nuclei travel down the pollen tube to reach and fertilize the egg cell, resulting in seed formation and ultimately fruit dispersal.
A woody plant is defined as a vascular plant that develops secondary xylem, also called wood. Wood is made of cellulose-reinforced cell walls in the xylem and provides strength. Woody plants evolved from seedless vascular plants and later gymnosperms in response to competition for light as plants colonized land. Today, all woody plants are seed plants, including both gymnosperms like conifers and angiosperm dicots. Woody plants are typically large perennials that develop wood, whereas non-woody plants are often herbaceous.
The document provides information about the reproductive biology of flowering plants (angiosperms). It discusses key events in angiosperm evolution such as the origin of flowers and fruits. It also summarizes the characteristics and life cycles of monocots and eudicots. Angiosperms have had a profound influence on the evolution of other organisms through symbiotic relationships like pollination and seed dispersal. Their success is largely due to adaptations like seeds that enabled colonization of new environments.
Gregor Mendel conducted experiments with pea plants to discover the laws of heredity and genetics. He found that each organism has two alleles for each trait, with one allele being dominant and observable in offspring while the recessive allele disappears. The alleles separate during gamete formation so each parent passes only one allele to each offspring randomly and independently for different traits. This helped explain how traits are inherited from parents to offspring.

Decolonizing Universal Design for LearningFrederic Fovet
ย
UDL has gained in popularity over the last decade both in the K-12 and the post-secondary sectors. The usefulness of UDL to create inclusive learning experiences for the full array of diverse learners has been well documented in the literature, and there is now increasing scholarship examining the process of integrating UDL strategically across organisations. One concern, however, remains under-reported and under-researched. Much of the scholarship on UDL ironically remains while and Eurocentric. Even if UDL, as a discourse, considers the decolonization of the curriculum, it is abundantly clear that the research and advocacy related to UDL originates almost exclusively from the Global North and from a Euro-Caucasian authorship. It is argued that it is high time for the way UDL has been monopolized by Global North scholars and practitioners to be challenged. Voices discussing and framing UDL, from the Global South and Indigenous communities, must be amplified and showcased in order to rectify this glaring imbalance and contradiction.
This session represents an opportunity for the author to reflect on a volume he has just finished editing entitled Decolonizing UDL and to highlight and share insights into the key innovations, promising practices, and calls for change, originating from the Global South and Indigenous Communities, that have woven the canvas of this book. The session seeks to create a space for critical dialogue, for the challenging of existing power dynamics within the UDL scholarship, and for the emergence of transformative voices from underrepresented communities. The workshop will use the UDL principles scrupulously to engage participants in diverse ways (challenging single story approaches to the narrative that surrounds UDL implementation) , as well as offer multiple means of action and expression for them to gain ownership over the key themes and concerns of the session (by encouraging a broad range of interventions, contributions, and stances).

14. Petals Stigma Anther Filament Ovary Sepals Ovules Nectaries Style Collect a cut-out flower, colour it in and put it together. Carpel female parts Stamen male parts
15. What do the parts do? Sepals- protect the flower when it is a bud Petals- colourful to attract the insects Nectaries- give out sugary liquid to attract insects Stamen - anther produces male sex cells (pollen) Carpel- stigma traps pollen Style is where pollen tube grows down to female sex cells. Carpel- ovary produces female sex cells (ovules)
28. Fertilisation Once fertilisation has taken place the zygote (fertilised ovule )becomes a seed , and the ovary becomes a fruit . The petals die and fall off. The plant seeds are in the fruit .

40. Tubers Tubers are underground food stores which stores food over the winter and provides a new plant with food until it can make its own. Food made by the new plant is sent to make new tubers. Thereby reproducing itself. Examples: potato, artichoke, yam, cassava, water chestnut, arrowroot Taro- Japanese potato
41. Arrowroot arrowroot = arrow root = Chinese potato (this name also is used for jicama ) = goo = seegoo = arrowhead = Chinese arrowhead = tse goo = ci gu = tsu goo Notes:ย ย The name arrowroot is more commonly associated with a thickener that's made from the plant. A fresh arrowroot tuber looks like a small onion, only without the layers. It should be peeled, and then it can be boiled or stir-fried. Look for it in Chinese markets during the winter.
42. Cassava cassava = casava = manioc = mandioca = tapioca root = yucca = yucca root = yuca root = Brazilian arrowrootย ย Pronunciation: ย ย kuh-SAH-vuh Notes: ย People in Hispanic countries use cassavas much like Americans use potatoes.ย There's both a sweet and a bitter variety of cassava. The sweet one can be eaten raw, but the bitter one requires cooking to destroy the harmful prussic acid it contains.ย
43. Topinambour tapioca root Notes:ย Water chestnuts are delightfully sweet and crisp- if you buy them fresh.ย You need to peel off their brown jackets and simmer them for five minutes before stir-frying. Tinned Water chestnuts are easily available but not nearly as good. If you use them, blanch them first in boiling water for thirty seconds.ย Topinambour Water chestnut Chinese water chestnut
44. Bulbs Bulbs are also underground food stores which work in the same way as tubers. The difference is that bulbs have thick fleshy โleavesโ. Keukenhof gardens near Amsterdam Holland.
46. 3. Dec. - Jan. Cooling Period Rest period. In order for bulbs to bloom in the spring they need weeks of at least 5 o C. Frost at this time doesnโt harm them. 1. Sept.- Oct. Planting Time The tulip bulbs are going to be planted twice as deep as the bulb is high. They have no roots at this stage. 2. November Making Roots The roots start growing out of the base, establish themselves taking nutrients from the soil. Mother bulbs get ready for winter. 4. Feb. โ March G rowing Period The bulbs begin to change as the starch, or carbohydrates in them turns to sugar. As this occurs, the leaves and flower gradually push up-wards out of the bulb. 5. April โ May B looming Time The tulips are in bloom-they receive their nourishment from the roots-only the brown skin of the bulb remains as all of the energy has gone to the bloom. 6. May โ June Regeneration After flowering the blooms are cut and the leaves are left on the plant. The new daughter-bulbs use the food in the leaves to grow. 7. July - Sept. Multiplying Up to five small bulbs can be expected to grow out of the mother bulb. They form their roots slowly, and develop their blooms and leaves within the bulb, for next year's plant.
47. Runners Runners are side shoots which grow out from the parent plant. Buds form at points along the runner and eventually these buds form roots and grow into new plants. Examples: spider plant ( Anthericum ), strawberry ( Fragaria x ananassa)
48. Flame violet ( Episcia reptans ) Collect Information Card โ Asexual Reproductionโ Take short notes from it.
49.
50. Reproduction- advantages Asexual Sexual Genetically identical offspring (clones) which have parentโs strong characteristics (but weak ones also passed on) and are suited to their environment. Narrow distribution spreading over the area quickly as no vulnerable stages involved. Genetically different offspring- variation . More chance of survival if conditions change. Wide distribution Reduces competition for water/light/nutrients as no dense growth around the parent. Using seeds allows the offspring to travel to new areas.
51.
52. Artificial Propagation People can make use of plantsโ ability to reproduce asexually (instead of using seeds) by using methods of artificial propagation such as: - Cuttings - Graftings Again this produces genetically identical offspring (clones).
53. Cuttings They can be placed in moist soil or water (and sometimes dipped in rooting powder). Cuttings are small pieces of stem with some leaves attached, the new plant grows from this.
54. Grafting A cut stem of one plant (with good flower or fruit growth) (the graft) is taken and firmly attached to the rootstock of another plant (which has a strong, established root system) (the stock) . Examples- roses, fruit trees
55. Grafting- advantages Allows you to clone the commercial qualities of a particular fruit variety on another tree. Seed trees have highly variable fruit quality. They come into production much earlier (2-3 years) than trees grown from seed (5-10 years).
