During secondary growth in dicot stems, the formation of phelloderm from phellogen is an example of which of the following developmental processes?

Step-by-step solution

Phellogen (cork cambium) is a secondary meristem formed by the process of dedifferentiation. When the cells of phellogen divide and the newly formed cells mature to form phelloderm (secondary cortex), they lose their capacity to divide. According to NCERT, the process by which the derivatives of a dedifferentiated tissue lose their ability to divide and mature to perform specific functions is called redifferentiation. Dedifferentiation is incorrect because it refers to the formation of the phellogen itself, not its
