Magnified Image of the Periderm in the image to the left. Periclinal Divisions in the Periderm produce cells predominately towards the Outside in radial files. If you trace a cell file backwards you will arrive at the Cork Cambium or Phellogen

Cork cells are dead at maturity!Peri-2-300Lab.jpg (28400 bytes) Consequently, all cells and tissues outside of the cork die. The Epidermis in the adjacent images is dead. Locate the Epidermis and note the presence of a Cuticle.
