Photo system 1 = Light

This is the presence of sunlight, whereby Chlorophyll is used to trap sunlight energy to split water molecules into hydrogen ions and hydroxyl ions also NADP is reduced by the addition of hydrogen to form NADH

Photo system II: Dark stage

It happens when there is abscence of light where by CO2 ingested by plants react with hydrogen atoms from the light stage to form the Emperial Formula of simple sugar. Also Hydroxyl ions (OH -) is furtherly broken-down to oxygen & molecules.

Photosynthesis is the process in which green plant manufacturer their food in the presence of Sunlight ND chlorophyll. Where CO2 (Carbon [iv] oxide) and water (H2O)
