Manganese is required in
nucleic acid synthesis
plant cell wall formation
photolysis of water during photosynthesis

photolysis of water during photosynthesis
In plants, manganese is absorbed in the form of manganous ions (Mn2+). It activates many enzymes involved in photosynthesis, respiration and nitrogen metabolism. The best-defined function of manganese is in the splitting of water to liberate oxygen during photosynthesis, ie, photolysis of water.
