How does a plant get food without shopping or eating? Imagine a tiny kitchen in every green leaf. The plant has no mouth or grocery bag, but it can cook. Soil isn't the meal. It supplies water and minerals; the leaf is the cooking space. Sunlight provides energy. Water comes through the roots, and carbon dioxide, a gas in the air, enters the leaves. These are the ingredients. Then comes the turn: the plant does not mainly get its food from soil. It makes sugar in its leaves using light, water, and carbon dioxide. This process is called photosynthesis: turning those ingredients into sugar while releasing oxygen. So how does it get food without eating? Its leaves run a solar-powered kitchen: sunlight supplies the energy, water and carbon dioxide become sugar, and oxygen is released back into the air.
