The green part of the plant is primarily involved in which of the following processes?

Which type of phosphorylation takes place in photosynthesis?

Consider the following statements.
$I.$ The portion of the spectrum between $300-500 \;nm$ is also referred to as Photosynthetically Active Radiation $(PAR)$.
$II.$ Magnesium,calcium and chloride ions play prominent roles in the photolysis of water.
$III.$ In cyclic photophosphorylation,oxygen is not released (as there is no photolysis of water) and $NADPH$ is also not produced.

Transpiration and Photosynthesis - a compromise. Give explanation.
