1. synthesis of chemical compounds with the aid of radiant energy and especially light especially formation of carbohydrates from carbon dioxide and a source of hydrogen (such as water) in the chlorophyll-containing cells (as of green plants) exposed to light
2. the process by which a green plant turns water and carbon dioxide into food when the plant is exposed to light
3. the process by which green plants and a few other organisms (as some protists) form carbohydrates from carbon dioxide and water in the presence of light
4. synthesis of chemical compounds with the aid of light sometimes including the near infrared or near ultraviolet especially the formation of carbohydrates from carbon dioxide and a source of hydrogen (as water) in chlorophyll-containing cells (as of green plants) exposed to light involving a photochemical release of oxygen through the decomposition of water followed by various enzymatic synthetic reactions that usually do not require the presence of light
