Explanation

Photosynthesis is how plants make their own food using sunlight energy. Plants take in carbon dioxide from air and water from soil. Sunlight powers the chemical reaction that transforms these raw materials into glucose sugar and oxygen gas.

The glucose serves as food that gives plants energy to grow and survive. The oxygen is released into the air as a waste product. This oxygen is what humans and animals breathe to stay alive.

Carbon dioxide and water are the raw materials plants need, not the products they make. Plants absorb these ingredients and change them into glucose for food and oxygen for breathing. This process happens mainly in leaves where chloroplasts capture sunlight.
