Quizplus · Accepted Answer

The light reactions in chloroplasts take place in the thylakoid disks, where pigments such as chlorophyll absorb light and convert it into chemical energy. The dark reactions, also known as the Calvin cycle, occur in the stroma of the chloroplasts, where carbon dioxide is fixed into organic molecules using the energy from the light reactions.
