Definition of cork cambium

Categorized under "General"

Definition as written by tiG:

A lateral ring of meristematic tissue found in woody seed plants, producing cork on the outside of the ring and parenchyma on the inside of the ring. Also called phellogen.
The function of cork cambium is to produce the cork, a tough protective material.
In places the cork cambium generates loose and disorganized cells so that the outer cork has pores (lenticels) that allow for oxygen uptake by the stem. In some trees the cork cambium forms a more or less continuous ring, leading to a smooth bark. When there are breaks in the cambium the bark will be fissured or scaly. In contrast to the vascular cambium the cork cambium can be renewed.
