Question

Which of the immune cells listed below are agranular?
P. Eosinophils
Q. Mast cells
R. Monocytes
S. T-cells

• A. P and Q only
• B. Q and R only
• C. R and S only
• D. S and P only

Hint:

Agranular cells, such as monocytes and T-cells, lack granules in their cytoplasm, which differentiates them from granular cells like eosinophils and mast cells.

Answer 1

The Correct Option is C

Step 1: Understand agranular cells.
Agranular cells are those immune cells that lack visible granules in their cytoplasm when viewed under a microscope. These include certain types of white blood cells like monocytes and T-cells.
Step 2: Analyze the options.
- (P) Eosinophils: These are granular cells, so they are not agranular.
- (Q) Mast cells: These are also granular cells, not agranular.
- (R) Monocytes: These are agranular cells, as they do not have prominent granules.
- (S) T-cells: These are also agranular cells.

Step 3: Conclusion.
The correct agranular cells are Monocytes (R) and T-cells (S), so the correct answer is (C).
