Q.

In tissue culture experiments, leaf mesophyll cells are put in a culture medium to form callus. This phenomenon may be called as:

  1. A

    Differentiation

  2. B

    Dedifferentiation

  3. C

    Development

  4. D

    Senescence

Solution

When already-differentiated mesophyll cells regain the capacity to divide and form an undifferentiated mass of callus, they have effectively reverted to a meristem-like state. This reversal of differentiation is called dedifferentiation.
