In eukaryotic plant cells, light-dependent reactions of photosynthesis take place specifically within which sub-compartment of the chloroplast?
A. Stroma
B. Thylakoid membranes✓ Correct Answer
C. Outer membrane
D. Intermembrane space
💡 Solution & Explanation
The light-dependent reactions of photosynthesis occur within the thylakoid membranes of chloroplasts, where chlorophyll traps solar energy. Conversely, the light-independent reactions, known as the Calvin cycle, take place in the surrounding fluid-filled stroma. Plant cell organelle specialization is a recurring theme in competitive biology questions.
