Therefore, the main difference between C3 and C4 plants is their metabolic reactions, operating during the dark reaction of photosynthesis. There are two different types of photosynthetic cells, which are ring-shaped, found surrounding the vascular tissues and are present within the leaves. has been found in a freshwater amphibious leafless sedge, Eleocharis vivipara (Ueno et al., 1988; Ueno, 1996a, 1996b). These are bundle sheath (BS) cells that surround the vascular centres, and mesophyll (M) cells that, in turn, surround the BS cells.
