Which cell type is not a granulocyte?

Which cell type is not a granulocyte?

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

Answer: (C)

Granulocytes are white blood cells that have visible granules in their cytoplasm. Among the options, neutrophils, eosinophils, and basophils all show these cytoplasmic granules and are considered granulocytes. Lymphocytes, however, do not have visible granules and have a large, round nucleus with only a thin rim of cytoplasm, classifying them as agranulocytes. Because of this lack of granules, the cell type that is not a granulocyte is the lymphocyte. Lymphocytes are key players in adaptive immunity, while the granulocytes pictured are more about immediate responses to infection or inflammation.
