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. 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.
