The oxygen liberated during photosymthesis comes from - (1) Water (2) Carbon dioxide (3) Glucose (4) Chlorophyll

1 Answer

Answer :

(1) Water Explanation: The oxygen produced during photosynthesis comes from water. The electrons excited by light in the chlorophyll molecule are replaced by electrons produced from the oxidation of water into oxygen. Photosynthesis combines water and carbon dioxide into sugars, leaving oxygen gas as a waste product.
