Plants' leaves consist of certain types of cells that contain little energy factories called chloroplasts. The chloroplasts contain chlorophyl, a green pigment that drives a chemical reaction that that takes the energy of light and uses it to convert water and carbon dioxide into sugar. This sugar is an energy source to make the plants grow.
