Where do the energy capturing reactions of photosynthesis occur?

Explanation

The energy-capturing reactions of photosynthesis, commonly referred to as the light-dependent reactions, occur in the thylakoids of chloroplasts. During these reactions, sunlight is absorbed by chlorophyll and other pigments in the thylakoid membranes, leading to the production of ATP and NADPH, which are crucial for the subsequent Calvin cycle in the stroma. The plasma membrane and cytoplasm are not involved in these specific reactions, and although the stroma is part of the chloroplast, it is the site of the Calvin cycle, not the light-dependent reactions.
