Which organelle carries out photosynthesis in plant cells?

Explanation:
Chloroplasts carry out photosynthesis in plant cells. They contain chlorophyll to capture light and have internal membrane systems (thylakoids) where the light-dependent reactions occur, producing ATP and NADPH and releasing oxygen from water. The Calvin cycle takes place in the surrounding fluid (the stroma) and uses those energy carriers to convert carbon dioxide into glucose. This specialization explains why chloroplasts do the photosynthetic work, while other organelles have different roles: mitochondria generate ATP through respiration, the nucleus stores genetic material, and the Golgi apparatus processes and ships cellular products.
