Answer: Glucose
The chloroplast during photosynthesis produce glucose under the light independent reactions. This happens due to some chemical reactions that convert carbon dioxide and other compounds into glucose. The process of these chemical reactions is called Calvin cycle, where it has three phases of light independent reactions, which are carbon fixation, reduction reactions and ribulose 1,5-bisphosphate (RuBP) regeneration. These reactions occurs in the stroma, the fluid filled area of chloroplast outside the thylakoid membrane.
