  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. 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. During locomotion, the endoplasm flows forwards and the ...

  4. Chaos (genus) - Wikipedia

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

    Chaos species are versatile heterotrophs, able to feed on bacteria, algae, other protists, and even small multicellular invertebrates. [4] Like all Amoebozoa, they take in food by phagocytosis, encircling food particles with its pseudopodia, then enclosing them within a food ball, or vacuole, where they are broken down by enzymes.

  5. Amoeba (genus) - Wikipedia

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

    Amoeba is a genus of single-celled amoeboids in the family Amoebidae. [2] The type species of the genus is Amoeba proteus , a common freshwater organism, widely studied in classrooms and laboratories.

  6. Holozoic nutrition - Wikipedia

    en.wikipedia.org/wiki/Holozoic_nutrition

    Amoeba, Entamoeba histolytica uses holozoic nutrition. Holozoic nutrition (Greek: holo -whole ; zoikos -of animals) is a type of heterotrophic nutrition that is characterized by the internalization ( ingestion ) and internal processing of liquids or solid food particles. [ 1 ]

  7. Primary nutritional groups - Wikipedia

    en.wikipedia.org/wiki/Primary_nutritional_groups

    Organotrophs use organic compounds as electron/hydrogen donors. Lithotrophs use inorganic compounds as electron/hydrogen donors.. The electrons or hydrogen atoms from reducing equivalents (electron donors) are needed by both phototrophs and chemotrophs in reduction-oxidation reactions that transfer energy in the anabolic processes of ATP synthesis (in heterotrophs) or biosynthesis (in autotrophs).

  8. Autotroph - Wikipedia

    en.wikipedia.org/wiki/Autotroph

    Thus, heterotrophs – all animals, almost all fungi, as well as most bacteria and protozoa – depend on autotrophs, or primary producers, for the raw materials and fuel they need. Heterotrophs obtain energy by breaking down carbohydrates or oxidizing organic molecules (carbohydrates, fats, and proteins) obtained in food.

  9. Bacterivore - Wikipedia

    en.wikipedia.org/wiki/Bacterivore

    A bacterivore is an organism which obtains energy and nutrients primarily or entirely from the consumption of bacteria.The term is most commonly used to describe free-living, heterotrophic, microscopic organisms such as nematodes as well as many species of amoeba and numerous other types of protozoans, but some macroscopic invertebrates are also bacterivores, including sponges, polychaetes ...
