A. The Calvin Cycle
Explanation:
The light-independent reactions cover half of photosynthesis, with the other half being the light-dependent reactions. Another word for this process is the Calvin cycle. It is named after the biologist, Melvin C. Calvin, who discovered it. The Calvin cycle is responsible for turning carbon dioxide into glucose. It also requires no light, hence its other name. Additionally, because it is occasionally called the Calvin cycle, sometimes, the light-dependent reaction is simply called the light cycle.
