Question

Which is not a function of epidermis?

• A. Protection from adverse condition.
• B. Gaseous exchange.
• C. Conduction of water.
• D. Transpiration.

Answer 1

The correct option is C

Conduction of water.

The correct option is C:

The conduction of water is carried out by Xylem.

Epidermis is a continuous layer of closely packed cells which lines the entire plant body. The major functions are;

1. Provide protection for the underlying plant tissue from outside environment.
2. Epidermal cells have specialized structures known as stomata which helps in the exchange of gases.
3. Stomata also helps in the process of transpiration( evaporation of water from leaves).

Thus, conduction of water is not a function of epidermis.
