Amoeba, Entamoeba histolytica uses holozoic nutrition. Holozoic nutrition (Greek: holo -whole ; zoikos -of animals) is a type of heterotrophic nutrition that is characterized by the internalization ( ingestion ) and internal processing of liquids or solid food particles. [ 1 ]
Amoeba proteus extending lobose pseudopodia. A pseudopod or pseudopodium (pl.: pseudopods or pseudopodia) is a temporary arm-like projection of a eukaryotic cell membrane that is emerged in the direction of movement. Filled with cytoplasm, pseudopodia primarily consist of actin filaments and may also contain microtubules and intermediate filaments.
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 ...
Thecamoeba is a genus of Amoebozoa with a tough pellicle simulating a shell.. It includes the species: T. aesculea Kudryavtsev & Hausmann 2009; T. assimilis Lepşi 1960; T. bilizi (Schaeffer 1926)
The food vacuole, or digestive vacuole, is an organelle found in simple eukaryotes such as protists.This organelle is essentially a lysosome.During the stage of the symbiont parasites' lifecycle where it resides within a human (or other mammalian) red blood cell, it is the site of haemoglobin digestion and the formation of the large haemozoin crystals that can be seen under a light microscope.
Entamoeba coli is a non-pathogenic species of Entamoeba that frequently exists as a commensal parasite in the human gastrointestinal tract. E. coli (not to be confused with the bacterium Escherichia coli) is important in medicine because it can be confused during microscopic examination of stained stool specimens with the pathogenic Entamoeba histolytica.

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.
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 ...
