Detailed explanation-1: -The light reaction of photosynthesis occurs in the presence of light which results in photolysis of water and it occurs in the grana of the chloroplast.

Detailed explanation-2: -Light reaction occurs in the presence of light in grana of the chloroplast. Dark reaction occurs in stroma of the chloroplast.

Detailed explanation-3: -The light reactions of photosynthesis take place in the thylakoid membrane, whereas the dark reactions are located in the chloroplast stroma.

Detailed explanation-4: -grana). The light-dependent reactions of photosynthesis take place within the thylakoids. These reactions occur when the pigment chlorophyll, located within the thylakoid membranes, captures energy from the sun (photons) to initiate the breakdown of water molecules.

Detailed explanation-5: -Light-dependent reactions happen in the thylakoid membrane of the chloroplasts and occur in the presence of sunlight. The sunlight is converted to chemical energy during these reactions. The chlorophyll in the plants absorb sunlight and transfers to the photosystem which are responsible for photosynthesis.
