In Kranz anatomy, the bundle sheath cells have
Thin walls, many intercellular spaces and no chloroplasts
Thick walls, no intercellular spaces and large number of chloroplasts
Thin walls, no intercellular spaces and several chloroplasts
Thick walls, many intercellular spaces and few chloroplasts
C4 plants have a characteristic leaf anatomy called Kranz anatomy. Kranz means wreath (ring) and is a reflection of the arrangement of cells. The large sized bundle sheath cells may form several layers around the vascular bundles. These cells are characterised by having a large number of agranal chloroplasts, thick walls impervious to gaseous exchange and no intercellular spaces.
