Photo Oxidation means knockout of electrons from a chemical compound in the presence of light by the high energy photons striking the compound and transferring their energy to the compound and thus knocking them out.

In case of plants photo oxidation is the same phenomenon (described above) , which leads to destruction of light capturing machinery chlorophyll. Accessory pigments like carotenoids play role in saving the plant from photo oxidation by absorbing the high intensity light.

I) photosynthesis is minimum in the green color as it reflects it all.

II) the 2 electrons produced go to the photosystem 2 where they are used to reduce the excited chlorophyll pigments.

Photolysis mean breakdown of molecules into smaller unit in the presences of light and photo respiration we can say the process by which in the presences of light plant consume oxygen and release carbon-dioxide gas during photosynthesis.

Photo oxidation means breaking down of chlorophyll molecules in the presnce of li8 by excess oxygen produced by plant during photosynhesis as a by product. 4 me theanswer should be c.

Photolysis is defined as the splitting of a chemical compound such as water into its component by light. For example water which is H2O would split into h+ & oh-.

Photooxidation:

Photo means light.
Oxidation this is addtion of oxygen and removal of hydrogen.
So, C is the correct answer.

Photolysis means breakdown of light in the presence of oxygen. It is also known as photo oxidation and photorespiration.

Photo means light, oxidation means addition of oxygen and removal of hydrogen. Lysis describes breakdown of molecules.

Photo oxidation is a process in which oxygen molecules are break down in the presence of light.

I think photooxidation means in which light and oxygen both are involved, so option D is right.

Photolysis is a chemical reaction in which a chemical compound is broken down by photons.
