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: -It is performed in the stroma of the chloroplast. The cytoplasm is the site of aerobic cellular respiration which breaks down the glucose into pyruvic acid and energy is liberated in the form of ATP. The pyruvic acid formed in the cytoplasm moves to the mitochondria and enters the Krebs cycle where energy is produced.

Detailed explanation-4: -The Calvin cycle is a progression of reactions that happens in the stoma of chloroplasts in a plant cell. The chemical reactions convert carbon dioxide into glucose with the assistance of ATP and NADPH. These reactions occur in the stoma, the inward space or fluid-filled region of a chloroplast.

Detailed explanation-5: -In $C 4$ plants, the Calvin cycle occurs in the stroma of bundle sheath chloroplasts.
