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 ...
If there are few food bacteria in that new environment, then the social amoeba are able to seed the area with the contained Burkholderia and thus develop a food source. Farmer amoebas do produce fewer spores in a food rich environment than non-farmer amoebas, but this cost is countered by farmers’ ability to replenish their food supply when ...
Amoebas (amoeboids) Pseudopods (Greek for false feet) are lobe-like appendages which amoebas use to anchor to a solid surface and pull themselves forward. They can change their shape by extending and retracting these pseudopods. [43] Amoeba: Found in every major protist lineage. Amoeboid cells occur among the protozoans, but also in the algae ...

They can change their shape by extending and retracting these pseudopods. [14] Amoeba: Found in every major protist lineage. Amoeboid cells occur among the protozoans, but also in the algae ...
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.
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.
This means primary producers become the starting point in the food chain for heterotroph organisms that do eat other organisms. Some marine primary producers are specialised bacteria and archaea which are chemotrophs , making their own food by gathering around hydrothermal vents and cold seeps and using chemosynthesis .
Amoeba proteus is a large species of amoeba closely related to another genus of giant amoebae, Chaos. As such, the species is sometimes given the alternative scientific name Chaos diffluens. [1] [2] Amoeba proteus in locomotion. This protozoan uses extensions called pseudopodia to move and to eat smaller unicellular organisms.
