Light reactions of photosynthesis occur in the:
AStroma of chloroplast (matrix fluid only)
BThylakoid membrane (with chlorophyll)
CCytoplasm of plant cell
DNucleus of plant cell
Answer & Solution
Correct answer: B. Thylakoid membrane (with chlorophyll)
Light reactions occur in the THYLAKOID MEMBRANE of the chloroplast (PSI, PSII, ATP synthase embedded there). Dark reactions (Calvin cycle) occur in the STROMA (fluid matrix).
