Why do plants need sunlight?
|
|
Plants make their own food by combining a gas called carbon dioxide, which they get from the air, with water from the soil. This process is called photosynthesis. To power the process, the plant uses the energy of sunlight. A green pigment in the leaves called chlorophyll traps the Sun's energy.
