Q.The formation of the cork cambium (phellogen) from mature, otherwise non-dividing parenchyma cells of a woody dicot stem, where those cells first regain the capacity to divide, is an example of:

[!TLDR]

Mature parenchyma cells regaining the capacity to divide (forming the cork cambium) is dediffe …

Dedifferentiation is specifically the reversal by which an already-differentiated, non-dividing mature cell regains the capacity to divide. The formation of the cork cambium (phellogen) from mature parenchyma cells of the cortex or epidermis of a woody stem is a standard example of this reversal, alongside the similar formation of the vascular cambium from interfascicular parenchyma. Differentiation is the opposite process (a dividi …

Identify the direction of change: a mature, non-dividing cell regaining division capacity is dedifferentiation, not differentiation (th …

Confusing dedifferentiation (mature cell regains division capacity) with redifferentiation (newly divided cells maturing into a specific ty …
