Characteristics of protozoans
What are the various characteristics of protozoans which make them look like animals?
Expert
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.
The evolutionary hypothesis which animal cells encompass come from the differentiation of protozoans is strong.
