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.
The kempyang and ketuk are two instruments in the gamelan ensemble of Indonesia, generally played by the same player, and sometimes played by the same player as the kenong. They are important beat-keepers in the colotomic structure of the gamelan. Depending on the structure, they play different, repeating patterns every gongan. Not all ...
A giant virus, Cafeteria roenbergensis virus (CroV) infects and causes the lysis of C. roenbergensis. [9] The impact of CroV on natural populations of C. roenbergensis remains unknown; however, the virus has been found to be very host specific, and does not infect other closely related organisms. [3]
[91] [92] There has been little research on mixotrophic protists, but recent studies in marine environments found mixotrophic protests contribute a significant part of the protist biomass. [87] Since protists are eukaryotes they possess within their cell at least one nucleus , as well as organelles such as mitochondria and Golgi bodies .
A protist (/ ˈ p r oʊ t ɪ s t / PROH-tist) or protoctist is any eukaryotic organism that is not an animal, land plant, or fungus.Protists do not form a natural group, or clade, but are a polyphyletic grouping of several independent clades that evolved from the last eukaryotic common ancestor.

Its field of study therefore overlaps with the more traditional disciplines of phycology, mycology, and protozoology, just as protists embrace mostly unicellular organisms described as algae, some organisms regarded previously as primitive fungi, and protozoa ("animal" motile protists lacking chloroplasts).
This classification remained widespread in the 19th and early 20th century, [7] and even became elevated to a variety of higher ranks, including phylum, subkingdom, kingdom, and then sometimes included within the similarly paraphyletic Protoctista or Protista.
