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 ]
In biology, a phylum (/ ˈ f aɪ l əm /; pl.: phyla) is a level of classification or taxonomic rank below kingdom and above class. Traditionally, in botany the term division has been used instead of phylum, although the International Code of Nomenclature for algae, fungi, and plants accepts the terms as equivalent.
Cercozoa (now synonymised with Filosa) [2] is a phylum of diverse single-celled eukaryotes. [4] [5] They lack shared morphological characteristics at the microscopic level, [6] and are instead united by molecular phylogenies of rRNA and actin or polyubiquitin. [7]
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] or Protozoa. [9]
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 ...
YouTube Music is a music streaming service developed by the American video platform YouTube, a subsidiary of Alphabet's Google.

Video albums by individual artists should not be put in this main category. Instead, they should be placed in their own subcategories of Category:Video albums by artist, under the format [[Category:(Artist name) video albums]]. The only video albums in this category should be compilation albums of many artists, or articles about series of video ...
[3] [4] There has been little research on mixotrophic protists, but recent studies in marine environments found mixotrophic protists contribute a significant part of the protist biomass. [5] Since protists are eukaryotes (and not prokaryotes) they possess within their cell at least one nucleus , as well as organelles such as mitochondria and ...
