What is difference between light reaction and dark reaction?

1.	What is difference between light reaction and dark reaction?
Answer» \tLight Reaction (light dependent reaction)Dark Reaction (light independent reaction)It occurs in thylakoid membranes of chloroplasts in a leaf.It occurs in the stroma of the living chloroplast.Light energy is absorbed by photosystems PS-I and PS-IICarbon dioxide present in the atmosphere is absorbed.Cyclic and non-cyclic photophosphorylation occur in the cellsC3 pathway is observed in green plants. In desert plants, we can observe c4 pathway.End products are ATP and NADP.H2.End products of light reaction are used up to synthesise sugar.Oxygen is released as a by-product of the photolysis if water.Main product is sugar in the form of glucose\t
