Type of Haemocyte | Morphology (shape/size) | Nucleus | Cytoplasm | Relative abundance |
---|---|---|---|---|
Prohaemocyte | Small (3-10 μm), spherical, oval, elliptical, high nucleo-cytoplasmic ratio | Large, centrally located; size is variable 3-12 μm | Devoid of inclusions | 12–16% |
Plasmatocyte | Polymorphic, spherical to oval, larger than prohaemocytes (up to 20 μm long), small nucleo-cytoplasmic ratio | Round or elongated, generally centrally located, occasionally binucleate | Basophilic, may be granular or agranular, | 35–52% |
Adipohaemocyte | Small to large (7–45 μm diameter), | Small, 4-10 μm diameter; round or slightly elongated; centric or eccentric | Contain small to large fat droplets, non-lipid granules, vacuoles | 23–42% |
Granulocytes | Spherical, 5–8 μm in diameter | Round and centrally located | Membrane bound inclusions found may be regular or irregular in shape | 5–11% |
Oenocytoid | Large cells (up to 25 μm) with regular rounded or oval shape, low nucleo-cytoplasmic ratio | Small (3–15 μm); round or elongate eccentric contains large nucleolus | Abundant | 1–2% of all the haemocytes present |
Disintegrated cell | No definite shape and size. Have ruptured cell membrane | Nuclear swelling, rupturing | Abnormal vacuolation, discharged cytoplasmic contents | 2–7% |
