Explanation

The inherent potentiality of a plant cell to give rise to a whole plant is described as cellular totipotency. The phenomenon of a mature cell reverting to the meristematic state and forming undifferentiated callus tissue is termed as dedifferentiation. The phenomenon of conversion of component cells of callus tissue to whole plant or plant organs is called as redifferentiation.
