What organelles are the site of photosynthesis?

Explanation:
Photosynthesis is carried out in chloroplasts, the green organelles in plant cells that contain the pigment chlorophyll. Inside chloroplasts, light-dependent reactions occur on the thylakoid membranes to produce energy-rich molecules, and the Calvin cycle takes place in the surrounding stroma to synthesize glucose from carbon dioxide. Mitochondria generate energy through cellular respiration, the nucleus stores genetic material, and ribosomes build proteins. Because chloroplasts are where light energy is converted into chemical energy stored as sugar, they are the site of photosynthesis.
