In Kranz anatomy, the bundle sheath cells have
In Kranz anatomy, the bundle sheath cells have
Options
- Athin walls, many intercellular spaces and no chloroplasts
- Bthick walls, no intercellular spaces and large number of chloroplasts
- Cthin walls, no intercellular spaces and several chloroplasts
- Dthick walls, many intercellular space and few chloroplasts
Correct answer
B. thick walls, no intercellular spaces and large number of chloroplasts
Step-by-step solution
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.
