Detailed explanation-1: -Photosynthesis occurs in the chloroplasts, the light-dependent reactions are located on the innermost membrane of chloroplasts called thylakoid membrane and light-independent reactions occur in the cytoplasm of the chloroplasts called stroma [17].

Detailed explanation-2: -The light independent process (also called dark reactions or the Calvin-Benson cycle) takes place in the stroma of the chloroplast. Carbon dioxide is modified by series of chemical reactions to form carbohydrates. The energy for these reactions comes from ATP and NADPH generated during the light dependent process.

Detailed explanation-3: -(i) Light reactions occur in grana thylakoids whereas dark reactions occur in stroma of chloroplasts.

Detailed explanation-4: -Dark reaction occurs in stroma of the chloroplast. Q. Photosynthesis involves a series of reactions. The light-dependent reactions occur in the presence of light while the light-independent reactions can occur in the light or dark.

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.
