All leaves change sunlight into energy through photosynthesis. The leaves are the primary food-making part of the plant. Leaves absorb carbon dioxide from the air, combine it with water that comes through the roots of the plants to make food (a sugar molecule known as glucose), and release oxygen into the air.
