Chloroplasts are the organelles in plant cells where photosynthesis occurs. They contain chlorophyll to capture light energy and drive the conversion of carbon dioxide and water into glucose, releasing oxygen. The light-dependent reactions take place in the thylakoid membranes, while the Calvin cycle operates in the stroma. Mitochondria generate energy through respiration, lysosomes digest materials, and peroxisomes handle fatty acid metabolism and detoxification; none of these carry out the light-driven production of chemical energy that defines photosynthesis.
