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.
Another type of white blood cells are the large granular cells which include NK cells and macrophages (which I work on) which have quite big nucleus and lots of cytoplasm. In their cytoplasm they have lots of granules (thus the name!) and they need these to perform their functions.
