Q. Manganese is required in:
A) Plant cell wall formation
B) Photolysis of water during photosynthesis
C) Chlorophyll synthesis
D) Nucleic acid synthesis
Explanation
[Solution from source] Manganese is a component of the water-splitting (oxygen-evolving) complex of photosystem II, so it is needed for photolysis of water and release of oxygen. Calcium (not manganese) is used in the middle lamella of the cell wall, and magnesium/iron are linked to chlorophyll synthesis. Answer (2).
