Specialised epidermal cells surrounding the guards cells are called

Options

A. Subsidiary cells
B. Bulliform cells
C. Lenticeles
D. Complementary cells

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the specialized epidermal cells that surround guard cells in plants.

2. **Identifying Guard Cells**: Guard cells are specialized cells located in the epidermis of leaves and are responsible for regulating the opening and closing of stomata, which are small pores that allow gas exchange.

3. **Surrounding Cells**: The cells that surround guard cells are known as accessory cells. These cells play a supportive role in the function of guard cells.

4. **Terminology**: The specialized epidermal cells surrounding guard cells are specifically referred to as "subsidiary cells." These cells are also sometimes called accessory cells.

5. **Eliminating Other Options**:
- **Bulliform Cells**: These are specialized cells that help in the folding of leaves to reduce water loss, not surrounding guard cells.
- **Lenticels**: These are small openings in the stems that facilitate gas exchange, not related to guard cells.
- **Complementary Cells**: These are associated with sieve tubes in phloem and are not related to guard cells.

6. **Conclusion**: The correct answer to the question is "subsidiary cells," which are specialized epidermal cells surrounding guard cells.

**Final Answer**: Subsidiary cells.
