A. PHOTOSYNTHESIS Photosynthesis n: A process by which green plants and other organisms produce simple carbohydrates from carbon dioxide and hydrogen, using energy that chlorophyll or other organic cellular pigments absorb from radiant sources.
They are also necessary to the energy exchange that living things need to survive. Photosynthesis is the process by which green plants create their own food by turning light energy into chemical energy. Chlorophyll in the leaves transform carbon dioxide, water, and minerals into oxygen and glucose.hey are also necessary to the energy exchange that living things need to survive.
