Callus is not produced in

The method of asexual reproduction in plants in which callus is produces is :

In tissue culture experiments of tobacco callus, it was seen that when the culture medium contains 2 ppm of IAA and 2ppm of kinetin, an undifferentiated mass of callus is produced. If the ratio of kinetin to IAA is increased, then

A : Callus is obtained within 2-3 weeks. R : Suspension culture grows much faster than callus culture.

A : Callus is obtained within 2-3 weeks. R : Suspension culture grows much faster than callus culture.

How callus is developed and what is the use of callus ? Explain.

(A) : Rapid cell divison in an explant can be induced with cytokinin. (R) : The mass of differentiated tissue produced is called callus.
