Answer 2

In plants, differentiation is the process where cells derived from root apical and shoot-apical meristems and cambium differentiate and mature to perform specific functions.  Once differentiated, the living plants cells lose the ability of division. However, under certain conditions, this ability of further division can be regained. The process where mature cells reverse their state of differentiation and acquire pluripotentiality is known asdedifferentiation. The process where dedifferentiated cells lose the power of division again and become specialized to perform a function by converting into a part of the permanent tissue is known as redifferentiation. This the key difference between dedifferentiation and redifferentiation
