The primary function of epidermis is

Options

A. Protection
B. Photosynthesis
C. Conduction of water and solute
D. Mechanical support

Answer

**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 underlying tissues.

2. **Identifying Functions**: The primary functions of the epidermis include:
- Protection against physical damage and pathogens.
- Regulation of gas exchange and transpiration through structures called stomata.
- Sometimes, it can also play a role in photosynthesis, but this is not its primary function.

3. **Analyzing the Options**:
- **Option 1: Protection** - This aligns with the primary function of the epidermis as it serves to protect the plant.
- **Option 2: Photosynthesis** - While some epidermal cells may contain chloroplasts, this is not the main role of the epidermis.
- **Option 3: Conduction of water and solute** - This function is primarily carried out by vascular tissues (xylem and phloem), not the epidermis.
- **Option 4: Mechanical support** - This is typically provided by other tissues like collenchyma and sclerenchyma, not the epidermis.

4. **Conclusion**: Based on the analysis, the primary function of the epidermis is protection.

**Final Answer**: The primary function of the epidermis is protection (Option 1).
