A. sunlight is absorbed by chlorophyll in a leaf
B. carbon dioxide is taken in from the air
C. water is transported from the roots
D. glucose is synthesized and distributed throughout the plant
E. oxygen is released
The process in green plants and certain other organisms by which carbohydrates are synthesized from carbon dioxide and a source of hydrogen (usually water), using light as an energy source. Most forms of photosynthesis release oxygen as a byproduct.

1. (Botany) (in plants) the synthesis of organic compounds from carbon dioxide and water (with the release of oxygen) using light energy absorbed by chlorophyll
2. (Microbiology) the corresponding process in certain bacteria
