 A granum (plural grana) is a stack of thylakoid discs.A thylakoid is a membrane-bound compartment inside chloroplasts.They are the site of the light-dependent reactions of photosynthesis. Pyrenoids are sub-cellular micro-compartments found in chloroplasts of many algaeThe stroma of a plant is the region outside of the thylakoid space; most of the enzymes essential in the process of photosynthesis are generally embedded in the stroma and in the thylakoid membranes.
