Answer:
The part of photosynthesis that does not require sunlight responses is called the carbon fixation phase.
Explanation:
Photosynthesis can be divided into two steps or phases, the light and the carbon fixation.
The phase called carbon fixation occurs in the chloroplast stroma and does not need sunlight to occur. This phase begins with the process of fixing carbon in an organic compound. At this stage, NADPH and ATP molecules produced in the light phase are used to produce sugars from the reduction of the fixed carbon. The reactions that occur here are called the Calvin Cycle, and in this process most of the fixed carbon is converted to sucrose or starch.
