Question

Cork cambium forms tissues that form the cork. Do you agree with this statement? Explain.

Answer 1

Yes. Cork cambium or phellogen is a secondary meristem that develops from pericycle of root and the hypodermal layer of the stem. Its cell show bipolar divisions ie., division both on the outer and inner side. The tissue formed outside is initially living and parenchymatous. Soon its wall become suberised. Living protoplasm dies. The empty cells get filled with tannins, alkaloids and air. The dead suberised tissue is called cork or phellem.
