Diagram of leaf with Kranz anatomy

Wreath of enlarged bundle sheath cells

Mesophyll cells radially arranged

Water-storage tissue in this xerophyte

A diagram of the Kranz (wreath) anatomy of saltbush (Atriplex sp.) leaf, a xerophytic plant. The radial arrangement of the mesophyll ensures that most of its cells are in contact with the bundle sheath cells. Note how prominent are the bundle sheaths in the leaf. While common, this structural arrangement is not the case with all C4 plants.

1 = vascular bundle, 2 = bundle sheath cell, 3 = radially arranged palisade mesophyll (Kranz-mesophyll) cell, 4 = water-storage parenchyma cell, 5 = stomatal complex, 6 = sub-stomatal cavity, 7 = cuticle of adaxial epidermis
