PHOTOSYNTHESIS definition : 1. the process by which a plant uses carbon dioxide from the air, water from the ground, and the…. Learn more. Photosynthesis plays a critical role in producing and maintaining the oxygen content of the Earth's atmosphere, and it supplies most of the biological energy necessary for complex life on Earth. [2] Some organisms also perform anoxygenic photosynthesis , which does not produce oxygen. The process by which green plants use sunlight to make their own food from carbon dioxide and water is known as photosynthesis . This is done in the presence of chlorophyll.
