In a plant cell the Calvin cycle takes place in the (a) Stroma of the chloroplast.
Calvin cycle is the C₃ cycle that occurs in majority of the plants. It includes three steps: carbon fixation, reduction and regeneration. The first carbon acceptor in C₃ cycle is RuBP (Ribulose 1,5-bisphosphate). RuBP and CO₂ combine together to form the Oxaloacetate. The reactions of Calvin cycle belong to the dark phase of photosynthesis.
Stroma of the chloroplast is the colorless liquid present inside the chloroplast double membrane, excluding the thylakoid region. It consists of various substances like the chloroplast DNA, ribosomes, and some enzymes for carbon fixation (Calvin cycle).
