Question

Which of the following is the correct pairing of types of white blood cells to their proper category?
A) agranulocyte; eosinophil
B) granulocyte; lymphocyte
C) agranulocyte; neutrophil
D) granulocyte; basophil
E) granulocyte; macrophage

Answer 1

Answer:

D) granulocyte; basophil

Explanation:

Granulocytes and agranulocytes are categories of white blood cells (cells responsible for protecting the body like policemen protect the society).

GRANULOCYTES:

They contain granules in their cytoplasm which are visible under the microscope.

Following cells are included in this category:

1. Neutrophils
2. Eosinophils
3. Basophils
4. Mast cells

AGRANULOCYTES:

These cells don't contain granules in their cytoplasm.

Following cells are included in this category:

1. Lymphocytes
2. Monocytes

Note: when monocyte leaves the blood circulation, enters the tissue and differentiates, it is then known as macrophage.

From the answer choices,

only option D) granulocyte; basophil is correctly matched. Other answer choices are incorrect.
