How photosynthesis works
In short: Leaves use light energy to turn carbon dioxide and water into sugar, releasing oxygen.
1. Chlorophyll, the green pigment in leaves, absorbs light energy. 2. Carbon dioxide from the air enters the leaf through tiny pores called stomata. 3. Water is carried up from the roots to the leaves. 4. The light's energy turns carbon dioxide and water into sugars such as glucose. 5. Oxygen is released into the air as a by-product.
