Amoeba (disambiguation)

Last updated

Amoeba (sometimes amœba or ameba, plural amoebae, amoebas or amebas) is a type of cell or organism which has the ability to alter its shape, primarily by extending and retracting pseudopods.

Amoeba polyphyletic group including different eucariot taxons

An amoeba, often called amoeboid, is a type of cell or unicellular organism which has the ability to alter its shape, primarily by extending and retracting pseudopods. Amoebas do not form a single taxonomic group; instead, they are found in every major lineage of eukaryotic organisms. Amoeboid cells occur not only among the protozoa, but also in fungi, algae, and animals.

'''

Amoebozoa phylum of protozoans

Amoebozoa is a major taxonomic group containing about 2,400 described species of amoeboid protists, often possessing blunt, fingerlike, lobose pseudopods and tubular mitochondrial cristae. In most classification schemes, Amoebozoa is ranked as a phylum within either the kingdom Protista or the kingdom Protozoa. In the classification favored by the International Society of Protistologists, it is retained as an unranked "supergroup" within Eukaryota. Molecular genetic analysis supports Amoebozoa as a monophyletic clade. Most phylogenetic trees identify it as the sister group to Opisthokonta, another major clade which contains both fungi and animals as well as some 300 species of unicellular protists. Amoebozoa and Opisthokonta are sometimes grouped together in a high-level taxon, variously named Unikonta, Amorphea or Opimoda.

Amoeba Music

Amoeba Music is a US independent music chain with stores in Berkeley, San Francisco, and Hollywood, Los Angeles, California. It was founded in 1990 in San Francisco's Haight-Ashbury district and remains in operation, having survived the decline of CD sales in the 2000s.

Amoeba is an experimental music group that fuses the pop and ambient music genres. They formed in California, United States, in 1992. The core members of the group are ambient musician Robert Rich and guitarist/bassist Rick Davies.

Amoeba (mathematics)

In complex analysis, a branch of mathematics, an amoeba is a set associated with a polynomial in one or more complex variables. Amoebas have applications in algebraic geometry, especially tropical geometry.

In mathematics, the amoeba order is the partial order of open subsets of 2ω of measure less than 1/2, ordered by reverse inclusion. Amoeba forcing is forcing with the amoeba order; it adds a measure 1 set of random reals.

Cell may refer to:

Pseudopodia A temporary protrusion or retractile process of a cell, associated with flowing movements of the protoplasm, and serving for locomotion and feeding.

A pseudopod or pseudopodium is a temporary cytoplasm-filled projection of an eukaryotic cell membrane or a unicellular protist. Pseudopods may be used for motility, or for ingesting nutrients or other particulate matter. Cells that make pseudopods are generally referred to as amoeboids. Pseudopods extend and contract by the reversible assembly of actin subunits into many microfilaments. Filaments near the cell's end interact with myosin which causes contraction. The pseudopod extends itself until the actin reassembles itself into a network.

Labyrinthulomycetes class of protists

The Labyrinthulomycetes (ICBN) or Labyrinthulea (ICZN) are a class of protists that produce a network of filaments or tubes, which serve as tracks for the cells to glide along and absorb nutrients for them. The two main groups are the labyrinthulids and thraustochytrids. They are mostly marine, commonly found as parasites on algae and seagrasses or as decomposers on dead plant material. They also include some parasites of marine invertebrates.

Face to Face (punk band) American punk rock band formed in 1991

Face to Face is a punk rock band from Victorville, California, formed in 1991 by front man Trever Keith, bassist Matt Riddle and drummer Rob Kurth. The band rose to fame with their 1995 album Big Choice, featuring the radio hit "Disconnected" that was first played on the radio and appeared in the movies Tank Girl and National Lampoon's Senior Trip.

Lobosa

Lobosa is a taxonomic group of amoebae possessing broad, bluntly rounded pseudopods. In current classification schemes, it is a subphylum of Amoebozoa, composed of amoebae that have lobose pseudopods but lack cilia or flagella.

<i>Adolescents</i> (album) album by the Adolescents

Adolescents, also known as The Blue Album due to its cover design, is the debut studio album by American punk rock band the Adolescents, released in April 1981 on Frontier Records. Recorded after guitarist Rikk Agnew and drummer Casey Royer joined the band, it features several songs written for their prior group, the Detours, including "Kids of the Black Hole" and "Amoeba", which became two of the Adolescents' most well-known songs. Adolescents was one of the first hardcore punk albums to be widely distributed throughout the United States, and became one of the best-selling California hardcore albums of its time. The band never toured in support of it, and broke up four months after its release. The Blue Album lineup of Agnew, Royer, guitarist Frank Agnew, bassist Steve Soto and singer Tony Brandenburg reunited several times in subsequent years, but only for brief periods.

<i>Chaos</i> (genus) genus of giant amoebae

Chaos is a genus of amoebae, in the family Amoebidae. The largest and best-known species, the so-called "giant amoeba", can reach lengths of 5 mm, although most specimens fall between 1 and 3 mm.

Chaos or CHAOS may refer to:

<i>Difflugia</i> genus of Tubulinea

Difflugia is the largest genus of Arcellinida, one of several groups of Tubulinea within the eukaryote supergroup Amoebozoa. Arcellinida species produce shells or tests from mineral particles or biogeonic elements and are thus commonly referred to as testate amoebae or shelled amoebae. Difflugia are particularly common in marshes and other freshwater habitats.

Polychaos dubium is a freshwater amoeboid and one of the larger species of single-celled eukaryote. Like other amoebozoans, P. dubium moves by means of temporary projections called pseudopods. P. dubium reportedly has one of the largest genome size of any organism known, though the authors of a 2004 study suggest treating that measurement with caution.

Protist unicellular organism of a diverse group of eukaryotic microorganisms

A protist is any eukaryotic organism that is not an animal, plant or fungus. The protists do not form a natural group, or clade, since they exclude certain eukaryotes; but, like algae or invertebrates, they are often grouped together for convenience. In some systems of biological classification, such as the popular five-kingdom scheme proposed by Robert Whittaker in 1969, the protists make up a kingdom called Protista, composed of "organisms which are unicellular or unicellular-colonial and which form no tissues".
