Which is not a function of epidermis?

Conduction of water
The conduction of water is not a function of the epidermis. The epidermis primarily serves as a protective outer layer of the plant.

Detailed Explanation:

The epidermis is the outermost layer of cells on the surface of plants. Its primary role is to protect the plant from adverse environmental conditions, including physical damage, water loss, and pathogen attack. The epidermis also participates in specific physiological functions such as:

1. Protection: The epidermis acts as a barrier to protect internal plant tissues.
2. Gaseous Exchange: Specialized openings called stomata regulate the exchange of oxygen, carbon dioxide, and water vapor.
3. Transpiration: It facilitates water loss in the form of vapor through the stomata, helping in temperature regulation and nutrient transport.

What the Epidermis Does Not Do:

• Water Conduction: This is not a function of the epidermis. The conduction of water is carried out by the xylem, a specialized vascular tissue.
