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 ...
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 ...
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.
Evosea is a strongly supported clade of eukaryotes containing four large groups of amoebozoans: Eumycetozoa or "true" slime molds, [3] Variosea, Cutosea and Archamoebae.It is defined on a node-based approach as the least-inclusive clade containing Dictyostelium discoideum (a true slime mold), Protostelium nocturnum (a variosean), Squamamoeba japonica (a cutosean), and Entamoeba histolytica (an ...
Lobosa is a taxonomic group of amoebae in the phylum Amoebozoa.Most lobosans possess broad, bluntly rounded pseudopods, although one genus in the group, the recently discovered Sapocribrum, has slender and threadlike (filose) pseudopodia. [1]
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.
The class Tubulinea, as of 2022, is classified into three major groups: Corycida, Echinamoebida and Elardia. The most taxonomically abundant group is Elardia, which contains the testate amoebae of Arcellinida and the naked amoebae of orders Leptomyxida and Euamoebida .
The Amoebidae are a family of Amoebozoa, [1] including naked amoebae that produce multiple pseudopodia of indeterminate length. These are roughly cylindrical with granular endoplasm and no subpseudopodia, as found in other members of the class Tubulinea.
