Answer:
Explanation:
Photosynthesis is broadly divided into two phases. The one is the light-dependent or light reactions and other is the light-independent or dark reactions. Both these phases occur in the chloroplast of a plant cell.
Light-dependent reactions occur in the thylakoid of the chloroplast. These reactions require light. The chlorophyll molecules absorb light and convert light energy into NADH and ATP. Light energy also breaks water molecules and releases oxygen.
Light-independent reactions do not require light and the reactions occur in the stroma of the chloroplast. Using power (NADH and ATP) synthesized during light reactions, carbon dioxide is reduced into sugar molecules.
