Detailed explanation-3: -At the time of maturity, the cork cells become dead and replace the epidermis layer of the stem or root with the outer boundary. The suberin does not allow the water and gases to go outside of the cork cells. It is overall protecting cork cells that are present on the barks of trees.

Detailed explanation-4: -The cork cambium or pericambium or Phellogen initially forms from the parenchyma cells in the cortex and at times in the primary phloem. It produces new dermal tissues which gradually replaces the epidermis which is formed by the protoderm.
