In which cell structure is chlorophyll located for photosynthesis?

• A. Chloroplasts
• B. Mitochondria
• C. Nucleus
• D. Vacuole

Answer: (A)

Chlorophyll is the green pigment that captures light energy for photosynthesis, and it sits inside chloroplasts. These plant cell organelles are where photosynthesis occurs, with the light-dependent reactions taking place in the thylakoid membranes that contain chlorophyll, and the Calvin cycle occurring in the surrounding stroma. The other organelles listed have different roles: mitochondria generate energy through respiration, the nucleus houses genetic material, and the vacuole stores water and maintains turgor. Since chlorophyll resides in chloroplasts and these are the sites of photosynthesis, that structure is the correct answer.
