(b) differentiation

(c) dedifferentiation

(d) redifferentiation

This question was posed to me by my school teacher while I was bunking the class.

My question comes from Plant Growth and Development in section Plant Growth and Development of Biology – Class 11

Answer 1

Correct option is (c) dedifferentiation

Explanation: Dedifferentiation is the phenomenon that leads to regaining the lost capacity of cells or tissues of plants to divide under special conditions. Dedifferentiation is regaining the lost capacity of cells or tissues of plants to divide under special conditions. Redifferentiation is the maturation of dedifferentiated cells thereby specializing for a particular function.  Development includes all the changes undergone by a living plant from seed emergence to death.
