The correct answer is: photolysis of water during photosynthesis
In plants, manganese is absorbed in the form of manganous ions $\left(\mathrm{Mn}^{2+}\right)$. 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.
