MICROANATOMY

Detailed explanation-1: -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.

Detailed explanation-2: -14.5 The dark reactions: the Calvin cycle. Carbon dioxide is fixed by a series of light-independent reactions, called the dark reactions, which utilize the NADPH and ATP generated by light-dependent electron transport within the thylakoid membranes.

Detailed explanation-3: -In eukaryotic cells, both the light and dark reactions of photosynthesis occur within chloroplasts-the light reactions in the thylakoid membrane and the dark reactions within the stroma.
