Question

Secondary cortex is produced by

• A. Cork cambium
• B. Inter fascicular cambium
• C. Intra fascicular cambium
• D. (A) and (B) both

Hint:

Secondary cortex (phelloderm) is derived from cork cambium (phellogen).

Answer 1

The Correct Option is A

The cork cambium, also known as phellogen, produces the secondary cortex (phelloderm) towards the inside and cork (phellem) towards the outside. It plays a key role in the formation of the protective outer layer during secondary growth.
- Inter fascicular and intra fascicular cambium contribute to vascular cambium, not secondary cortex.
