Carbon dioxide is converted into an acid and transported into the bundle sheath cells where it will be … WebThe permeability of the bundle-sheath cell interface to metabolites is, therefore, about ten times that of C 3 mesophyll cells, whereas the conductance to CO 2 is more than a hundred times lower (Hatch, 1992). In some C 4 species, this is probably due to the presence of a layer of suberin in the bundle-sheath cell wall.

WebThe bundle sheath cells have RuBisCO but lack PEPcase; Carbon Fixation in CAM Plants.
