  2. Amoeboid movement - Wikipedia

    en.wikipedia.org/wiki/Amoeboid_movement

    In the first the cell extends small pseudopods which then move down the sides of the cell, acting like paddles. [9] [10] [12] In the second the cell generates an internal flow cycle, with the cytoplasm flowing backward along the membrane edge and forward through the middle, generating a force on the membrane which moves the cell forward. [10] [12]

  3. Protist locomotion - Wikipedia

    en.wikipedia.org/wiki/Protist_locomotion

    Cells which use flagella for movement are usually referred to as flagellates, cells which use cilia are usually referred to as ciliates, and cells which use pseudopods are usually referred to as amoeba or amoeboids. Other protists are not motile, and consequently have no built-in movement mechanism.

  4. Amoeba - Wikipedia

    Clockwise from top right: Amoeba proteus, Actinophrys sol, Acanthamoeba sp., Nuclearia thermophila., Euglypha acanthophora, neutrophil ingesting bacteria. An amoeba (/ ə ˈ m iː b ə /; less commonly spelled ameba or amœba; pl.: amoebas (less commonly, amebas) or amoebae (amebae) / ə ˈ m iː b i /), [1] often called an amoeboid, is a type of cell or unicellular organism with the ability ...

  5. Idionectes - Wikipedia

    en.wikipedia.org/wiki/Idionectes

    The protist can exist in two different forms: flagellate and amoeboid. It is the only known species of cutosean amoebas having both forms, [ 8 ] as all other cutoseans are non-flagellated. [ 9 ] As a flagellate, it projects out a single flagellum of about 30 μm long from the basal body and lives as a free swimmer in water. [ 1 ]

  6. 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 ...

  7. Amoebidae - Wikipedia

    en.wikipedia.org/wiki/Amoebidae

    In some cases the cell moves by "walking", with relatively permanent pseudopodia serving as limbs. The most important genera are Amoeba and Chaos, which are set apart from the others by longitudinal ridges. The best known of the species in this family is Amoeba proteus, commonly used in classrooms to demonstrate movement by pseudopodia.

  8. Protistology - Wikipedia

    en.wikipedia.org/wiki/Protistology

    The history of the study of protists has its origins in the 17th century. Since the beginning, the study of protists has been intimately linked to developments in microscopy , which have allowed important advances in the understanding of these organisms due to their generally microscopic nature.

  9. Pseudopodia - Wikipedia

    en.wikipedia.org/wiki/Pseudopodia

    A common example of this type of amoeboid cell is the macrophage. They are also essential to amoeboid-like locomotion. Human mesenchymal stem cells are a good example of this function: these migratory cells are responsible for in-utero remodeling; for example, in the formation of the trilaminar germ disc during gastrulation.
