Question

5. Agranulocyte that moves like amoeba and engulf foreign materials A) Lymphocyte B) Monocyte C)Acidphils D) Neutrophil

​

Answer 1

Answer:

Lymphocytes

Explanation:

Lymphocytes are agranulocytes, ie WBC's are classified as granulocytes(Neutrophil, Eosinophil and Basophil ) and agranulocytes(Monocytes and Lymphocytes). In this, 'Lymphocytes' are a type of WBC's that are transported through lymph vessels and through lymph nodes, that play a crucial role in defense mechanism, ie it engulf foreign materials and kill them. They keep circulating through out lymph vessels and are a part of immune system.

Answer 2

Correct answer is B) Monocytes

Explanation:

• Monocytes are agranulocytes, they lack granules in their cytoplasm
• When Monocytes leaves blood and enter into tissue they differentiated into macrophage
• Macrophage move like amoeba and they can form Pseudopodia that enclose the foreign material into a vesicle and engulf them and digest the foreign material. The process is called phagocytosis.
• Lymphocytes are agranulocytes but they can not perform phagocytosis.
• Acidophil and neutrophil are granulocyte
• So correct answer is B) monocytes
