The Calvin cycle occurs in the stroma of chloroplasts in plant cells. It does not require light directly, as it is termed a "light-independent" reaction. However, it relies on the ATP and NADPH produced during the light-dependent reactions of photosynthesis, which do require light. Therefore, while the Calvin cycle can take place in the absence of light, it is ultimately dependent on the products generated during the light reactions.
