Which statement is true for both photosynthesis and cellular respiration they require oxygen as a reactant they require organelles. they require light energy from the sun. they require cells to use water

Ans.

Photosynthesis is a process that results in synthesis of food from light energy and carbon dioxide, in which oxyge releases as byproduct. Cellular respiration is a process that results in breakdown of food (generally carbohydrates) to release energy, and carbon dioxide is released as a byproduct. Only Photosynthesis requires water and sun engery to process, whereas oxygen is used in cellular respiration only.

Both the processes, cellular respiration and photosynthesis require cell organelles to occur as Photosynthesis occurs in chloroplasts of eukaryotic cells, while cellular respiration occurs in mitochondria of ekmukaryotic cells.
