Plants can be classified into different types depending on their shape and size. Their main parts include leaves, stems, flowers, fruits, and roots. Plants are useful as they provide food, medicine, wood, paper, oxygen and help with shelter and shade. They can grow in different environments around the world like forests, grasslands, mountains, and tundra. Certain fruits and vegetables are transported to India from other countries due to variations in climate. Orchards are areas where fruit trees are grown and groves contain grouped trees.
