Amoebas are a genus of the Protozoa. They are unicellular, eukaryotic microorganisms, which have one or more nuclei and a contractile vacuole for the purpose of maintaining osmotic equilibrium. They obtain food through phagocytosis, making them heterotrophs. The defining characteristic that makes them eukaryotic, is their membrane-bounded nuclei, which houses they deoxyribonucleic acid.
