Which organelle contains chloroplasts and is the site of photosynthesis in plant cells?

Explanation:
Photosynthesis happens in chloroplasts, organelles that contain the pigment chlorophyll and the internal membranes where light-dependent reactions occur. The light reactions use solar energy to split water and transfer energy to produce ATP and NADPH, which then fuel the Calvin cycle in the stroma to build sugars from carbon dioxide. This makes chloroplasts the site where this energy-to-sugar conversion happens in plant cells. Other organelles have different roles: mitochondria generate ATP through respiration, the nucleus stores genetic material, and the endoplasmic reticulum makes proteins and lipids.
