Amoeba vs. Euglena — What's the Difference?

An amoeba (; less commonly spelt ameba or amœba; plural am(o)ebas or am(o)ebae ), often called an amoeboid, is a type of cell or unicellular organism which has the ability to alter its shape, primarily by extending and retracting pseudopods. Amoebae do not form a single taxonomic group; instead, they are found in every major lineage of eukaryotic organisms.

Euglena is a genus of single cell flagellate eukaryotes. It is the best known and most widely studied member of the class Euglenoidea, a diverse group containing some 54 genera and at least 800 species.

Any of various one-celled free-living or parasitic protozoans having no definite form and moving by means of pseudopods.

Any of various single-celled freshwater organisms of the genus Euglena, characterized by the presence of chlorophyll, a reddish eyespot, a single long anterior flagellum, and a second, rudimentary flagellum.

(biology) A member of the genus Amoeba of unicellular protozoa that moves by means of temporary projections called pseudopodia.

(biology) Any of several protists, of the genus Euglena, that contain chloroplasts and a single flagellum.

(mathematics) The graph of the real part of the logarithms of a polynomial equation in complex numbers.

Minute single-celled green freshwater organism having a single flagella; often classed as algae

(slang) An asexual.

A rhizopod common in fresh water, capable of undergoing many changes of form at will. Same as ameba. See Rhizopoda.

Naked freshwater or marine or parasitic protozoa that form temporary pseudopods for feeding and locomotion
