In Kranz anatomy, the bundle sheath cells have

In Kranz anatomy, the bundle sheath cells have
  1. thin walls, many intercellular spaces and no chloroplasts
  2. thick walls, no intercellular spaces and large number of chloroplasts
  3. thin walls, no intercellular spaces and several chloroplasts
  4. thick walls, many intercellular space and few chloroplasts

Solution

$\mathrm{C}_4$ 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.
