a. Differentiation

b. De-differentiation

c. Redifferentiation

Solution:

a) Differentiation: the cell of the apices of roots, apices of shoot and cambium can differentiate and mature so that they can perform specific functions.

b) De-differentiation: When a differentiated cell is exposed to appropriate conditions, it can regain its ability to divide..

c) Redifferentiation: It’s a condition in which undifferentiated cells lose their ability to divide.
