During the process of photosynthesis in green plants, where do the light-dependent reactions primarily take place?
A. Stroma of the chloroplast
B. Thylakoid membranes of the chloroplast✓ Correct Answer
C. Outer envelope of the chloroplast
D. Cytoplasm of the plant cell
💡 Solution & Explanation
The light-dependent reactions occur within the thylakoid membranes of chloroplasts, where chlorophyll pigments absorb solar energy to drive photolysis of water and produce adenosine triphosphate and NADPH. The light-independent carbon fixation reactions take place in the surrounding fluid region known as the stroma. Oxygen released during photosynthesis originates from the splitting of water molecules during the light reactions.
