Protists are distributed across all major groups of eukaryotes, including those that contain multicellular algae, green plants, animals, and fungi. If photosynthetic and fungal protists are distinguished from protozoa, they appear as shown in the phylogenetic tree of eukaryotic groups.
The names of some protists (called ambiregnal protists), because of their mixture of traits similar to both animals and plants or fungi (e.g., slime molds and flagellated algae like euglenids), have been published under either or both of the botanical and the zoological codes of nomenclature.
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.
This category contains valid protist species names, i.e. eukaryotes that are not plants, fungi or animals. Alternate names (i.e. junior synonyms) are not included here.. Italicized entries are articles about species in monotypic genera; these are redirected to their appropriate genus ar
[1] [2] The group was first suggested by Simpson and Patterson in 1999 [3] [4] and the name latinized and assigned a rank by Thomas Cavalier-Smith in 2002. It contains a variety of free-living and symbiotic protists, and includes some important parasites of humans such as Giardia and Trichomonas. [5]
Protists are the eukaryotes that cannot be classified as plants, fungi or animals. They are mostly unicellular and microscopic.Many unicellular protists, particularly protozoans, are motile and can generate movement using flagella, cilia or pseudopods.
Amoebozoa are a group of motile amoeboid protists, members of this group move or feed by means of temporary projections, called pseudopods.The best known member of this group is the slime mold, which has been studied for centuries; other members include the Archamoebae, Tubulinea and Flabellinia.
