Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Where does the Calvin cycle take place?
A
stroma of the chloroplast
B
thylakoid membrane
C
outer membrane of the chloroplast
D
interior of the thylakoid membrane
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: -The Calvin cycle is present in all photosynthetic eukaryotes and also many photosynthetic bacteria. In plants, these reactions occur in the stroma, the fluid-filled region of a chloroplast outside the thylakoid membranes.

Detailed explanation-3: -The Calvin cycle or the light independent reactions of photosynthesis take place in the stroma of the chloroplast. The stroma is the fluid space surrounding the grana of chloroplast. The light dependent reactions occur in the thylakoid membrane.

Detailed explanation-4: -Calvin cycle is also known as the C3 cycle. It is the cycle of chemical reactions where the carbon from the carbon cycle is fixed into sugars. It occurs in the chloroplast of the plant cell.

Detailed explanation-5: -The light-independent reactions of photosynthesis take place within the stroma. It contains enzymes that work with ATP and NADPH to “fix” carbon from carbon dioxide into molecules that can be used to build glucose.
