Question

Agranulocytes are
A) Eosinophils
B) Neutrophils
C) Basophils
D) None of the above

Answer 1

Hint: Agranulocytes are a type of white blood cells or WBCs which have no distinct granules present in their cytoplasm.

Complete Answer:
Before we find the correct answer, let us know a little bit about WBCs. White blood cells or leukocytes are colourless cells which are found in blood and help in protecting the body from various kinds of infections. It is majorly of two types, Agranulocytes and Granulocytes.

Option A: Eosinophils are an example of granulocytes and not agranulocytes. Therefore, this is the incorrect option.

Option B: Neutrophils are an example of granulocytes and not agranulocytes. Therefore, this is the incorrect option.

Option C: Basophils are an example of granulocytes and not agranulocytes. Therefore, this is the incorrect option.

Option D: As none of the above options are correct, therefore this is the correct option.
Agranulocytes comprises of two cells,
Monocytes - They help in fighting bacteria, fungi and viruses.
Lymphocytes - They have an important role in producing antibodies.

Thus, the correct option is D) None of the above.

Note: The functions of granulocytes,
- Neutrophils - They are the first cells to fight against a foriegn body and help in destruction of bacteria and also acts as a strong oxidant.
- Eosinophils - They help in controlling various mechanisms which are associated with asthma and allergy and fight against infections in parasites.
- Basophils - They have a role in non- specific immune response towards allergic reactions and pathogens by dilating blood vessels and releasing histamine.
