Where does the Calvin Cycle occur?
A
thylakoid
B
stroma
C
lumen
D
mitochondria
Explanation: 

Detailed explanation-1: -Unlike the light reactions, which take place in the thylakoid membrane, the reactions of the Calvin cycle take place in the stroma (the inner space of chloroplasts).

Detailed explanation-2: -In plants, carbon dioxide (CO2) enters the chloroplast through the stomata and diffuses into the stroma of the chloroplast-the site of the Calvin cycle reactions where sugar is synthesized. The reactions are named after the scientist who discovered them, and reference the fact that the reactions function as a cycle.
