Question

The process in which water is split during photosynthesis is

• A. Photolysis
• B. Hydrolysis
• C. Plasmolysis
• D. Hemolysis

Answer 1

The correct option is A Photolysis

Photolysis of water occurs at grana i.e., lumen side of grana thylakoid membrane with the help of water splitting complex or OEC (oxygen evolvong complex). This step is associated with PS- II of Z- scheme.

Three minerals Mn ion, ${Ca}^{+}+,{Cl}^{-}$ are associated with splitting of water.

So, the correct answer is 'Photolysis'.
