Question

Grafting is not successful in monocots but is successful in
dicots because they have

• A. Vessels with elements arranged end to end
  
• B. Cambium for secondary growth
  
• C. Cork cambium
  
• D. Vascular bundles arranged in a ring
  

Answer 1

The correct option is B Cambium for secondary growth


Grafting - successful in dicots

Grafting disrupts the vascular system and regeneration of the vascular system is necessary to maintain normal transportation of water and nutrients.

Monocots have no vascular cambium, which is a lateral meristematic tissue capable of dividing and adding to secondary growth.

Thus regeneration of tissues is impossible, making grafting impossible.

Final answer:

(b) Cambium for secondary growth
