Which plant cell organelle is primarily involved in photosynthesis?

Explanation:
Photosynthesis in plants happens mainly in chloroplasts, the green organelles that contain chlorophyll. These structures capture light energy and drive the chemical reactions that turn carbon dioxide and water into glucose, with oxygen released as a byproduct. Inside chloroplasts, the thylakoid membranes carry out the light-dependent reactions, while the surrounding stroma performs the Calvin cycle to build sugar. This is why chloroplasts are the primary site of photosynthesis in plant cells. The nucleus controls cell activities and houses DNA, mitochondria generate ATP via respiration (not light-driven sugar production), and ribosomes synthesize proteins.
