What if a plant seems to eat nothing at all-how does it make its food? Think of the plant as a tiny kitchen. Soil supplies water and minerals through the roots, but soil is not the plant's meal. The kitchen needs three things: sunlight, water, and carbon dioxide from the air. Sunlight is the energy that powers the cooking; water and carbon dioxide are the ingredients. Here's the turn: the plant is not eating food from the soil. It uses sunlight to make sugar. That sugar becomes energy and material for growth. And while the plant is cooking, another substance comes out: oxygen, released into the air. This process is called photosynthesis-the plant's way of making food with light. So, how can a plant eat without a meal? It cooks its own: sunlight helps turn water and carbon dioxide into sugar, while oxygen is released.
