  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. Chromatoidal bodies - Wikipedia

    en.wikipedia.org/wiki/Chromatoidal_bodies

    It is thought that the chromatoidal body formation is a manifestation of parasite-host adaptive conditions. Ribonucleoprotein is synthesized under favorable conditions, crystallized in the resistant cyst stage and dispersed in the newly excysted amoebae when the amoeba is able to establish itself in a new host. [1]

  4. Amebocyte - Wikipedia

    en.wikipedia.org/wiki/Amebocyte

    Similarly to some of the white blood cells of vertebrates, in many species amebocytes are found in the blood or body fluid (e.g. as the blood cells of Limulus, the horseshoe crab) [1] and play a role in the defense of the organism against pathogens. Depending on the species, an amebocyte may also digest and distribute food, dispose of wastes ...

  5. Amoeboid movement - Wikipedia

    en.wikipedia.org/wiki/Amoeboid_movement

    Amoeboid movement is the most typical mode of locomotion in adherent eukaryotic cells. [1] It is a crawling-like type of movement accomplished by protrusion of cytoplasm of the cell involving the formation of pseudopodia ("false-feet") and posterior uropods.

  6. 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.

  7. Symbiosis in Amoebozoa - Wikipedia

    en.wikipedia.org/wiki/Symbiosis_in_Amoebozoa

    This social cycle results in a differentiation between cells: ~20% are sacrificed to form a structural stalk, [10] some transform into sentinel cells with immune like and detoxifying functions, [4] and the rest of the aggregated amoeba form a ball of spores located in protective fruiting body. [8]

  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. Archaeocyte - Wikipedia

    en.wikipedia.org/wiki/Archaeocyte

    Cellular differentiation is an essential function of the archaeocyte. All specialized cells within the sponge have its origins with the archaeocyte. This is especially important in reproduction as the sex cells of the sponge in sexual reproduction are formed from these amoeboid cells.
