noun

  1. the biological synthesis of chemical compounds in the presence of light
  2. the production of organic substances, chiefly sugars, from carbon dioxide and water occurring in green plant cells supplied with enough light to allow chlorophyll to aid in the transformation of the radiant energy into a chemical form
