The light-dependent reactions of photosynthesis take place in the:
AThe cell nucleus
BThe cytoplasm
CThylakoid membranes
DRibosome surfaces
Answer & Solution
Correct answer: C. Thylakoid membranes
1. A chloroplast has two very different internal compartments.
2. The membranes stacked inside it hold the pigment complexes.
3. The light-dependent reactions occur in the thylakoid membranes of chloroplasts.
4. The Calvin cycle occurs in the stroma of chloroplasts instead.
