(ii) The size varies from 10-30µ (iii) The outline shows finger like pseudopodia. (iv) Actively motile in nature. (v) Cytoplasm: Ectoplasm—prominent; Endoplasm—finely granular with ingested RBCs Vacuoles—scanty, spherical and defined. Nucleus: Nuclear membrane uniformly stained with chromatin; karyosome is [...]
