Which of the following statements about cork cambium is incorrect?

A It is a couple of layers thick
B It forms secondary cortex on its outerside
C It forms a part of periderm
D It is responsible for the formation of lenticels

Verified Solution

Answer & Solution

Correct Answer

(B) It forms secondary cortex on its outerside

Step-by-step Solution

Detailed explanation

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.

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
