The taxon 'Protozoa' fails to meet these standards, so grouping protozoa with animals, and treating them as closely related, became no longer justifiable. The term continues to be used in a loose way to describe single-celled protists (that is, eukaryotes that are not animals, plants , or fungi ) that feed by heterotrophy . [ 9 ]
A protist (/ ˈ p r oʊ t ɪ s t /) is any eukaryotic organism (one with cells containing a nucleus) that is not an animal, plant, or fungus.The protists do not form a natural group, or clade, since they exclude certain eukaryotes with whom they share a common ancestor; [a] but, like algae or invertebrates, the grouping is used for convenience.

Ciliate species range in size from as little as 10 μm in some colpodeans to as much as 4 mm in length in some geleiids, and include some of the most morphologically complex protozoans. [ 4 ] [ 5 ] In most systems of taxonomy , " Ciliophora " is ranked as a phylum [ 6 ] under any of several kingdoms , including Chromista , [ 7 ] Protista [ 8 ...
The parasitologist F. E. G. Cox noted that "Humans are hosts to nearly 300 species of parasitic worms and over 70 species of protozoa, some derived from our primate ancestors and some acquired from the animals we have domesticated or come in contact with during our relatively short history on Earth". [3]
It gets its name from the combination of "Sarcodina" (which is an older term used for amoeboids) [4] and "Mastigophora" (which is an older term for flagellates).. The characteristics of phylum sarcomastigophora are :
Protozoa from "Zenon: Girl of the 21st Century" was basically the the coolest rockstar to come from Outer Space. He was a heartthrob to Zenon and girls and boys everywhere, and we all just wanted ...
Protistology is a scientific discipline devoted to the study of protists, a highly diverse group of eukaryotic organisms. All eukaryotes apart from animals, plants and fungi are considered protists. [1]
