Where does the dark phase occur?

Photosynthesis is a process that takes place in the chloroplasts of plant cells. It used to be thought that it only proceeds in sunlight. But it turned out that there is also a dark phase. During the dark phase, glucose is synthesized. It can be stored with the help of special cellular inclusions in the form of starch grains. Glucose is the main source of energy for all life on our planet. During the light phase, other processes occur with the release of oxygen. First of all, the synthesis of ATP.
