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.
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]
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.
Systematists today do not treat Protista as a formal taxon, but the term "protist" is still commonly used for convenience in two ways. [22] The most popular contemporary definition is a phylogenetic one, that identifies a paraphyletic group: [23] a protist is any eukaryote that is not an animal, (land) plant, or (true) fungus; this definition [24] excludes many unicellular groups, like the ...
It could cover the articles on protist taxa, but also the relationships between different groups of eurkaryotes, including those with their own projects. Protists is rather unsatisfying group for the 21st century and this project would either be handling non-photosynthetic protists or overlap considerably with the algae.
Some modern authors prefer to exclude multicellular organisms from the traditional definition of a protist, restricting protists to unicellular organisms. [9] [10] This more constrained definition excludes all brown, the multicellular red and green algae, and, sometimes, slime molds (slime molds excluded when multicellularity is defined as ...
This project aims to cover all areas of microbiology including: bacteria, archaea, fungi, protists, viruses, microbiologists, microbiological methods and concepts, microbiology equipment, microscopy, and other microbiology-related topics.
Welcome to WikiProject Protista! This is a collaboration group created to improve Wikipedia's coverage and organization of information about the eukaryotic organisms known as protists or protoctists , from which all other eukaryotes have evolved: plants , fungi and animals .
