Here's a breakdown:

* Granulocytes are white blood cells that have granules in their cytoplasm. Examples include neutrophils, eosinophils, and basophils.

* Agranulocytes are white blood cells that lack granules in their cytoplasm. Examples include lymphocytes and monocytes.

So, "agranulocyte" specifically refers to a cell type that lacks the characteristic granules found in other white blood cells.
