Q. What are the characteristics of protozoans that make them resemble animals?

Protozoans are unicellular beings with some related characteristics to animal cells.

In comparison to pluricellular organisms protozoans are more proximal to the animal kingdom than to plants they are heterotrophs, they have a rudimentary locomotion system amoeboid movements, flagella, cilia, they do not have cell wall some species present structures that resemble structures of a primitive digestive system with cytostome (mouth) and cytopyge (anus) specialized in digestion and excretion.

The evolutionary hypothesis that animal cells have come from discrimination of protozoans is strong.
