Basophil  - least common, release histamines, lg. puplish granules

  Eosinophil- Bilobed  red nucleus, Digest parasitic worms                                               

  Neutrophils -  Most numerous, Multilobed nucleus, Release histamines

                                                            

                                                                     

Agranulocytes     Cytoplasmic granules do not "appear" to absorb dye
