Which of the following cells does not exhibit phagocytic activity ?

Options

A. Monocyte
B. Basophil
C. neutrophils
D. Macrophage

Answer

To determine which of the following cells does not exhibit phagocytic activity, we will analyze each option provided:

1. **Monocytes**:
- Monocytes are a type of white blood cell that can differentiate into macrophages and dendritic cells. They are known for their ability to engulf and digest pathogens and debris, thus exhibiting phagocytic activity.

2. **Basophils**:
- Basophils are another type of white blood cell, but they primarily play a role in allergic reactions and inflammation. They release substances such as heparin, serotonin, and histamine, which are involved in these processes. Basophils do not perform phagocytosis.

3. **Neutrophils**:
- Neutrophils are the most abundant type of white blood cells and are highly effective at phagocytosing bacteria and fungi. They are key players in the immune response and exhibit strong phagocytic activity.

4. **Macrophages**:
- Macrophages are derived from monocytes and are well-known for their phagocytic capabilities. They can engulf and digest pathogens, dead cells, and other debris, thereby playing a crucial role in the immune system.

Based on this analysis, the cell that does not exhibit phagocytic activity is **Basophils**.

**Final Answer**: B. Basophils
