How does a plant get food without eating? A leaf is its tiny kitchen. Sunlight supplies the power; water and carbon dioxide, a gas in the air, are ingredients. But the leaf isn't just catching sunlight; it uses that energy to make sugar. That's photosynthesis: the leaf's recipe for making sugar with light. Oxygen is released as the recipe's other output. So what feeds the plant? Its leaves make sugar with that recipe: water, carbon dioxide, and sunlight's power.
