Plants purify air by which process?
Photorespiration
Photosynthesis
Photophosphorylation
Transpiration
B.
Photosynthesis
During photosynthesis, carbon dioxide is reduced into carbohydrates and oxygen is liberated, ie, plants purify air by process of photosynthesis.
Photorespiration is a respiratory process by which they take up oxygen in the light and give out some carbon dioxide, contrary to the general pattern of photosynthesis. It takes place in higher plants.
Photophosphorylation is the synthesis of ATP from ADP and phosphate that occurs in a plant using radiant energy absorbed during photosynthesis.
Transpiration is the process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor and is released to the atmosphere. It is the evaporation of water from plant leaves.
