Plants need three things for photosynthesis to occur: sunlight, water, and carbon dioxide. The sun's light, or energy, is absorbed by the chlorophyll in the cells of the plant. Water is taken from the soil and travels through the plant's root system. Carbon dioxide enters the plant's leaves through tiny openings called stomata.

Once the plant has all of its ingredients, the process can begin. First, energy that the plant has collected from the sun splits the water .....
