C₄ cycle has been associated with a particular leaf structure, called Kranz anatomy, typical Kranz anatomy exhibits an inner ring of bundle sheath cells around vascular tissues and an outer layer of mesophyll cells. This particular leaf anatomy generates a diffusion barrier that is

 a.) separates the uptake of atmospheric carbon in mesophyll cells from CO2 assimilation by rubisco in bundle sheath cells

 b.) limits the leakage of CO2 from bundle sheath to mesophyll cells

 c.) diffusion gradients—not only between but also within the cells—guide the shuttling of metabolites between the two compartments that operate the C4 cycle

 d.)  Bundle sheath cells surround the vascular tissue, while an outer ring of mesophyll cells is peripheral to the bundle sheath and adjacent to intercellular spaces and the percolates metabolites are transfer to the whole plant cell by vascular tissue
