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 ...
The most important genera are Amoeba and Chaos, which are set apart from the others by longitudinal ridges. The best known of the species in this family is Amoeba proteus , commonly used in classrooms to demonstrate movement by pseudopodia.
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.
The CDC has reported cases of "Naegleria fowleri" -- a brain eating amoeba -- because many people are choosing to irrigate their sinuses incorrectly.
It includes the 'archetypal' amoebae, known as the naked lobose amoebae or 'gymnamoebae' [104] (such as Amoeba itself), [105] among which is a genus of sorocarp-forming slime moulds, Copromyxa. [106] Some gymnamoebae are important pathogens to animals (e.g., Acanthamoeba ). [ 107 ]
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 ...
Archamoebae are a diverse group of amoebae.Many have flagella for motility, while others do not. They grow in the absence of oxygen, though some can tolerate small amounts
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 ...
