In c4 plants the bundle sheath cells are
WebC 4 photosynthesis requires the integrated functioning of mesophyll and bundle-sheath cells of leaves and is characterized by a CO 2 concentrating mechanism that allows Rubisco, located in the bundle-sheath cells, to function at high CO 2 concentrations. WebFor plants adapted to particularly hot environments, the first compound formed has 4 carbon atoms, hence C4 photosynthesis. In these plants, RuBisCO is restricted to the bundle sheath cells of the leaf. Carbon dioxide is converted into an acid and transported into the bundle sheath cells where it will be converted back into CO 2.

WebBundle sheath cells C4 plants have a special kind of anatomy called Kranz anatomy, in which the bundle sheath cells form several layers around the vascular bundles. The … WebC 4 plants concentrate CO 2 into the bundle sheath (BS) cells where Rubisco is localized. This leads to more efficient photosynthesis in warm climates and thus facilitates domination of open landscapes of low-to-mid latitude. C 4 photosynthesis also allows exotic C 4 grasses to become aggressive weeds.
