What are the main parts of a plant? The main parts are roots, stem, leaves, flowers, and fruits. What is the function of the roots? Roots anchor the plant in the soil and absorb water and nutrients. How do plants make their food? Plants make food through photosynthesis, using sunlight, carbon dioxide, and water to produce glucose and oxygen. What is the role of the stem? The stem supports the plant, transports water and nutrients between the roots and leaves, and holds the leaves up to the light. Why are leaves important? Leaves are where photosynthesis occurs; they capture sunlight and exchange gases. What are stomata and what do they do? Stomata are small openings on the underside of leaves that allow for gas exchange; they let carbon dioxide in and oxygen out. How do flowers contribute to a plant's life cycle? Flowers are involved in reproduction; they produce seeds that grow into new plants. What is pollination and why is it important? Pollination is the transfer of pollen from the male part of the flower to the female part, which allows for fertilization and the production of seeds.
