Groupings. The granular leukocytes are the neutrophils, the eosinophils and the basophils. The agranular cells are the monocytes and the lymphocytes. The basis for the division of the white blood cells into these two groups is the presence of granules inside the granular cells.
All white blood cells are nucleated, which distinguishes them from the anucleated red blood cells and platelets. Types of leukocytes can be classified in standard ways. Two pairs of broadest categories classify them either by structure (granulocytes or agranulocytes) or by cell lineage (myeloid cells or lymphoid cells).
