Why is grafting not possible in monocots?

A
As they lack cambium

B
As they are herbaceous

C
As they have scattered vascular bundles

D
As they have parallel venation

Solution

Key to success in any grafting is to connect the cambium of the scion with the cambium of the root stock.
Monocots lack cambium in the vascular bundle in between xylem and phloem. Hence, grafting is not possible in monocots.

Vertically with morphological apical end upwards

B
Vertically with morphological basal end upwards

C
