Which organelle captures light energy for photosynthesis?

Explanation:
Chloroplasts are the organelles that capture light energy for photosynthesis. They contain chlorophyll, the green pigment that absorbs sunlight. That light energy powers the chemical processes inside chloroplasts that turn carbon dioxide and water into glucose (sugar) and oxygen, giving plants their food and energy. Mitochondria release energy from sugar, the nucleus stores genetic material, and ribosomes build proteins, so they aren’t the light-capturing site.
