The right answer is Both convert energy from one form to another.
Photosynthesis is a biochemical reaction that takes place only in plants and not in animals.
Photosynthesis creates energy in the form of carbohydrate from light energy, oxidizing water and reducing carbon dioxide.
Cellular respiration is the set of metabolic processes that convert the chemical energy contained in carbohydrates (such as glucose) into ATP (adenosine triphosphate), an energetic substrate used by the cell.
