The document describes the main plant parts and their functions. It explains that roots hold the plant in place and take in water and food from the soil. The stem stands the plant up and transports water and food throughout. Leaves breathe in carbon dioxide from the air and use energy from the sun to produce food for the plant through photosynthesis. Flowers attract insects to pollinate them so they can produce seeds. Plants provide beauty, food, shelter and more benefits to habitats.
