03 Do Plants Have Mouths?

Through the process of photosynthesis, plants make food by taking in light through their leaves. The leaves contain a chemical called chlorophyll, which is what makes the leaves green. Plants use their roots to bring in water that is full of nutrients from the soil. They absorb sunlight and carbon dioxide through their leaves. These leaves use the water and nutrients from the roots, along with the sunlight and carbon dioxide, to make a special sugar that the plant uses for energy.
