Question

Which of the following statements about cork cambium is incorrect?

(1) It is a couple of layers thick

(2) It forms secondary cortex on its outerside

(3) It forms a part of periderm

(4) It is responsible for the formation of lenticels

Answer 1

Answer (2) It forms secondary cortex on its outerside

Sol. Cork cambium (Phellogen) is dedifferentiated tissue, so it is a secondary meristem. It is couple of layers thick and cuts off cork (Phellem) towards outer side and secondary cortex (Phelloderm) towards inner side

Phellem + Phellogen + Phelloderm together constitute periderm.
