  2. Taxonomy of Protista - Wikipedia

    en.wikipedia.org/wiki/Taxonomy_of_Protista

    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.

    en.wikipedia.org/wiki/Protist

    The five-kingdom model remained the accepted classification until the development of molecular phylogenetics in the late 20th century, when it became apparent that protists are a paraphyletic group from which animals, fungi and plants evolved, and the three-domain system (Bacteria, Archaea, Eukarya) became prevalent. [166]

  4. Amoebozoa - Wikipedia

    en.wikipedia.org/wiki/Amoebozoa

    Amoebozoa is a major taxonomic group containing about 2,400 described species of amoeboid protists, [8] often possessing blunt, fingerlike, lobose pseudopods and tubular mitochondrial cristae. [ 7 ] [ 9 ] In traditional classification schemes, Amoebozoa is usually ranked as a phylum within either the kingdom Protista [ 10 ] or the kingdom ...

    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]

    The characteristics of phylum sarcomastigophora are : (1) Nucleus is of one type except in the stages of certain foraminifera. (2) Locomotory organ either pseudopodia or flagella or both. (3) Reproduction asexual, but when sexually it is essentially by syngamy. Example : Amoeba, Euglena etc.

  7. Kingdom (biology) - Wikipedia

    en.wikipedia.org/wiki/Kingdom_(biology)

    The five kingdom system may be combined with the two empire system. In the Whittaker system, Plantae included some algae. In other systems, such as Lynn Margulis's system of five kingdoms, the plants included just the land plants (Embryophyta), and Protoctista has a broader definition. [12] [page needed]

  8. Excavata - Wikipedia

    en.wikipedia.org/wiki/Excavata

    It contains a variety of free-living and symbiotic protists, and includes some important parasites of humans such as Giardia and Trichomonas. [5] Excavates were formerly considered to be included in the now obsolete Protista kingdom. [ 6 ]

  9. Zooflagellate - Wikipedia

    en.wikipedia.org/wiki/Zooflagellate

    In some older systems of classification, Zoomastigophora is a phylum (more commonly known as zooflagellates) within the kingdom Protista.Organisms within this group have a spherical, elongated body with a single central nucleus.
