Which of the following cells does not exhibit phagocytic activity ?

Options

A. Monocytes
B. Neutrophil
C. Basophil
D. Macrophage

Explanation

To determine which of the following cells does not exhibit phagocytic activity, we need to analyze the functions of each cell type listed in the options: monocytes, neutrophils, basophils, and macrophages.

### Step-by-Step Solution:

1. **Understand Phagocytosis**:
- Phagocytosis is the process by which certain cells engulf and digest foreign particles, such as bacteria and dead cells. Cells that exhibit this activity are known as phagocytes.

2. **Identify the Cell Types**:
- **Monocytes**: These are a type of white blood cell that can differentiate into macrophages and dendritic cells. They are involved in immune responses and can perform phagocytosis.
- **Neutrophils**: These are the most abundant type of white blood cells and are essential in the body's defense against infections. They are highly effective phagocytes, targeting bacteria and fungi.
- **Basophils**: These are the least common type of granulocytes and are primarily involved in allergic reactions and inflammatory responses. They do not perform phagocytosis.
- **Macrophages**: These are differentiated monocytes that reside in tissues and are potent phagocytes, capable of engulfing and digesting pathogens and debris.

3. **Analyze Each Option**:
- **Monocytes**: Exhibit phagocytic activity.
- **Neutrophils**: Exhibit phagocytic activity.
- **Basophils**: Do not exhibit phagocytic activity; they are involved in allergic responses.
- **Macrophages**: Exhibit phagocytic activity.

4. **Conclusion**:
- Among the options provided, the cell that does not exhibit phagocytic activity is **Basophils**.

### Final Answer:
**Basophils** do not exhibit phagocytic activity.
