Question

When we peel the skin of a potato tuber, we remove

• A. periderm
• B. epidermis
• C. cuticle
• D. sapwood

Answer 1

The correct option is A periderm

The potato periderm is the outer tissue of potato tubers that protects the tuber from pathogen attack, dehydration and wounding during harvest and storage. It is secondary in origin and replaces the epidermis early during tuber development. The outer layers of the periderm consist of cells with suberized walls. The layers of cork, cork cambium and secondary cortex constitute the protective covering called periderm.

When we peel the skin of a potato tuber, we remove periderm.

So, the correct answer is 'Periderm'.
