Which is not a function of epidermis?

Options

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

Explanation

**Step-by-Step Solution:**

1. **Understanding the Epidermis**: The epidermis is the outermost layer of cells in plants. It serves as a protective barrier for the plant body.

2. **Functions of the Epidermis**: The main functions of the epidermis include:
- **Protection from Desiccation**: It prevents water loss from the plant.
- **Protection from Pathogens**: It acts as a barrier against bacteria, viruses, and fungi.
- **Gaseous Exchange**: The stomata, which are part of the epidermis, allow for gas exchange (such as oxygen and carbon dioxide) and transpiration (water vapor loss).

3. **Identifying the Options**: The question asks for a function that is NOT associated with the epidermis. The options typically include:
- Protection from adverse conditions
- Gaseous exchange
- Transpiration
- Conduction of water and minerals

4. **Analyzing Each Option**:
- **Protection from Adverse Conditions**: This is a function of the epidermis as it protects against water loss and infection.
- **Gaseous Exchange**: This is also a function of the epidermis due to the presence of stomata.
- **Transpiration**: This process is facilitated by the epidermis through stomata.
- **Conduction of Water and Minerals**: This is NOT a function of the epidermis. Instead, conduction is the role of vascular tissues like xylem.

5. **Conclusion**: The correct answer is that the conduction of water and minerals is not a function of the epidermis.

**Final Answer**: The conduction of water and minerals is not a function of the epidermis.
