Cork cambium is a meristematic tissue that arises as a result of dedifferentiation of ________ in dicot roots.
Cork cambium is the lateral meristem. It is a secondary meristem that means it has formed after the dedifferentiation of the parenchymatous cells. The parenchyma cells of the epidermis give rise to the cork cambium, which then divides to form cork cells on the outer side and secondary cells on the inner side. Hence, the correct answer is ‘Epidermal cells’
