Explanation

Chlorine, manganese, and calcium help in the photolysis of water during the photosynthetic light reaction. Photolysis of water refers to the breakdown of water molecules into hydrogen and oxygen in the presence of light during the light reaction of photosynthesis. Water photolysis is aided by the micronutrients manganese and chlorine.
