Agranulocytes are leukocytes without granules; which of the following is an agranulocyte?

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

Answer: (D)

Agranulocytes are leukocytes without cytoplasmic granules when stained. Among common white blood cells, lymphocytes and monocytes are agranulocytes, while neutrophils, eosinophils, and basophils are granulocytes because they contain visible granules. Lymphocytes are typically smaller cells with a large nucleus that fills most of the cell and only a thin rim of cytoplasm, and they lack cytoplasmic granules. This makes lymphocytes the agranulocyte among the options. In the body, lymphocytes are central to adaptive immunity, forming B cells, T cells, and NK cells. The other options are characterized by cytoplasmic granules and are therefore granulocytes.
