Question

The term periderm is used to denote

• A. Cortex
• B. Secondary cortex
• C. Both A and B
• D. None of the above

Answer 1

The correct option is C Both A and B

The periderm is the secondary protective dermal tissue that replaces the epidermis during growth in thickness of stems and roots of gymnosperms and dicotyledons i.e., secondary growth.

Unlike typical epidermis, the periderm is a multilayered tissue system, the bulk of which usually constitutes the cork or phellem. It also has secondary cortex.

Hence the correct option is C.
