  2. Amoeba - Wikipedia

    en.wikipedia.org/wiki/Amoeba

    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 ...

  3. Amoeba (genus) - Wikipedia

    en.wikipedia.org/wiki/Amoeba_(genus)

    In Amoeba, the pseudopodia are approximately tubular, and rounded at the ends (lobose). The cell's overall shape may change rapidly as pseudopodia are extended and retracted into the cell body. An Amoeba may produce many pseudopodia at once, especially when freely floating. When crawling rapidly along a surface, the cell may take a roughly ...

  4. Amoebozoa - Wikipedia

    en.wikipedia.org/wiki/Amoebozoa

    An amoeba of the genus Mayorella (Amoebozoa, Discosea). Amoebozoa is a large and diverse group, but certain features are common to many of its members. The amoebozoan cell is typically divided into a granular central mass, called endoplasm, and a clear outer layer, called ectoplasm.

  5. Pseudopodia - Wikipedia

    en.wikipedia.org/wiki/Pseudopodia

    Amoeba proteus extending lobose pseudopodia. A pseudopod or pseudopodium (pl.: pseudopods or pseudopodia) is a temporary arm-like projection of a eukaryotic cell membrane that is emerged in the direction of movement. Filled with cytoplasm, pseudopodia primarily consist of actin filaments and may also contain microtubules and intermediate filaments.

  6. Amoeba proteus - Wikipedia

    en.wikipedia.org/wiki/Amoeba_proteus

    The locomotion of Amoeba proteus exhibits chaotic dynamics described by a low-dimensional chaotic attractor with a correlation dimension around 3-4, indicating that the seemingly random movement arises from deterministic cooperative interactions among a small number of processes like sol-gel transformations, cytoplasmic streaming, and calcium-mediated reactions. [7]

  7. Chaos (genus) - Wikipedia

    en.wikipedia.org/wiki/Chaos_(genus)

    Chaos is a genus of single-celled amoeboid organisms in the family Amoebidae.The largest and most-known species, the so-called "giant amoeba" (Chaos carolinensis), can reach lengths up to 5 mm, although most specimens fall between 1 and 3 mm. [3] [4] [5]

  8. Dictyostelium discoideum - Wikipedia

    en.wikipedia.org/wiki/Dictyostelium_discoideum

    Life cycle. Dictyostelium discoideum is a species of soil-dwelling amoeba belonging to the phylum Amoebozoa, infraphylum Mycetozoa.Commonly referred to as slime mold, D. discoideum is a eukaryote that transitions from a collection of unicellular amoebae into a multicellular slug and then into a fruiting body within its lifetime.

  9. Tubulinea - Wikipedia

    en.wikipedia.org/wiki/Tubulinea

    This class was anticipated by some biologists such as Jahn, who grouped all amoebae with granular pseudopodia together, [1] but most split the lobose amoebae into testate Testacealobosia and naked Gymnamoebia. These latter are polyphyletic, but molecular trees by Bolivar et al. [2] identified a core monophyletic subgroup.
