For some biologists, symbiosis includes “parasitism”, in which one member of the association, the host, suffers while the parasite gains from it; “mutualism” in which both components co-operate and gain from the interaction; and “commensalism” in which the association is neutral for one o

What Is a Protozoon?,actory. The idea that protozoa are unicellular in the sense that they correspond to a single cell of a multicellular organism was first conceived about 200 years after their discovery by Leeuwenhoek in 1674. The term “Protozoa” was coined by Goldfuss in 1817 to mean “original animals” and he included the coelenterates.
