State True or False: Each stoma is surrounded by a pair of kidney-shaped cells called accessory cells.

Answer

To determine whether the statement "Each stoma is surrounded by a pair of kidney-shaped cells called accessory cells" is true or false, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Terms**:
- A stoma (plural: stomata) is a small opening on the surface of leaves that allows for gas exchange.
- The cells that surround each stoma are known as guard cells, not accessory cells.

2. **Identifying the Correct Cells**:
- Guard cells are typically described as being kidney-shaped and are responsible for regulating the opening and closing of the stoma.
- Accessory cells, on the other hand, do not surround the stoma; they are a different type of cell.

3. **Evaluating the Statement**:
- The statement claims that the cells surrounding the stoma are called accessory cells. Since we established that these cells are actually guard cells, the statement is incorrect.

4. **Conclusion**:
- Therefore, the statement "Each stoma is surrounded by a pair of kidney-shaped cells called accessory cells" is false.

### Final Answer:
The statement is **False**.
