Plants need sun, water, air and soil to survive. They have different parts like leaves, stems, roots and flowers. Leaves absorb sunlight and oxygen, roots absorb water and minerals, and stems support the plant. There are different types of plants like trees, bushes and grass. Some plants lose their leaves in autumn while evergreen trees keep their leaves all year. Plants reproduce through seeds contained in fruit or through pollen carried by wind or insects. Plants are important as they provide food, oxygen and homes for animals.
