Question

Which of the following cells of the immune system do not perform phagocytosis?

• A. Macrophage
• B. Neutrophil
• C. Eosinophil
• D. Basophil

Hint:

Remember that basophils are involved in inflammation and allergic responses but do not perform phagocytosis.

Answer 1

The Correct Option is D

To answer this question, we need to understand the function of different immune system cells and their role in phagocytosis.
(1) Macrophages: Macrophages are one of the primary phagocytic cells of the immune system. They engulf and digest pathogens, dead cells, and debris. Therefore, they perform phagocytosis.
(2) Neutrophils: Neutrophils are another type of white blood cell that actively participate in phagocytosis. They are the first responders to infection and help fight bacteria by engulfing them. Thus, they also perform phagocytosis.
(3) Eosinophils: Eosinophils are primarily involved in combating parasitic infections and allergic reactions. While they have some ability to perform phagocytosis, they are not as specialized in this function as macrophages or neutrophils. However, they can perform phagocytosis in certain conditions.
(4) Basophils: Basophils are a type of white blood cell that play a role in inflammatory responses, particularly in allergies. However, they do not perform phagocytosis. They release histamine and other chemicals but do not engulf pathogens.
Conclusion: The correct answer is Option 4: Basophil as basophils do not perform phagocytosis.
