The number of chloroplasts in the bundle-sheath cells is more than that in the mesophyll cells. When submerged plants are exposed to aerial conditions, they rapidly produce new photosynthetic tissues with C4-like traits. In the majority of plants, including rice, CO 2 is first fixed into a compound with three carbons (C 3) by the photosynthetic enzyme ribulose bisphosphate carboxylase oxygenase (Rubisco) – this is known as C 3 photosynthesis. Such anatomy is typical of sub-merged aquatic plants; traits typical of … Using this TO-GCN, we inferred and experimentally Significance The high starch content of mesophyll cells suggests they may benefit from an internal source of CO 2, for example via C 4 metabolism, and are also sites of starch storage.

The primary function of kranz anatomy is to provide a site in which CO 2 can be concentrated around RuBisCO, thereby avoiding photorespiration . Rhynchospora rubra was found to have a low CO2 compensation point, high δ13C value, Kranz leaf anatomy, starch present in the bundle sheath cells and the Kranz cells are also smaller than those in the terrestrial form (Figures 2C and 2D). The primary function of Kranz anatomy is to provide a site in which CO2 can be concentrated … Mesophyll and bundle sheath cells are connected through numerous cytoplasmic sleeves called plasmodesmata whose permeability at leaf level is called bundle sheath conductance. The results suggest that the lack of detectable photorespiration in C(4) plants is not related to leaf anatomy. The amphibious leafless sedge Eleocharis vivipara develops C4-like traits as well as Kranz anatomy under terrestrial conditions, but it develops C3-like traits without Kranz anatomy under submerged conditions.
