Protozoans are unicellular beings with certain identical characteristics to animal cells.
In comparison to pluricellular organisms protozoans are much proximal to the animal kingdom than to plants: they are heterotrophs, they contain a rudimentary locomotion system (that is, amoeboid movements, flagella and cilia), they do not contain cell wall, certain species present structures which resemble structures of a primitive digestive system, with cytostome (or mouth) and cytopyge (or anus), specialized in excretion and digestion.
