What is ameoba. Give a detail discription?
An amoeba is a highly motile eukaryotic, unicellular organism.

Typically belonging to the kingdom protozoa, it moves in an “amoeboid” fashion. As such, microbiologists often use the term “amoeboid”, to refer to a specific type of movement and amoebae interchangeably. Interestingly, amoebae are not a distinct taxonomic group and are, instead, characterized based on their “amoeboid” movement rather than distinct morphological characteristics. Moreover, even members of the same species can appear dissimilar. Amoebae species can be found in all major eukaryotic lineages, including fungi, algae and even animals.
Amoeba contain an endoplasm that is granular in nature. This granular endoplasm contains the nucleus and various engulfed food vacuoles. In addition, amoebae are eukaryotic by definition and possess a unique nucleus that contains a central karyosome with a thin layer of beaded chromatin coating the inner nuclear membrane; However, unlike many eukaryotes, amoebae are anaerobic. Thus, amoebae contain no mitochondria and generate ATP exclusively via anaerobic means.

Amoebas can be classified as free-living and parasitic. Parasitic amoebas are ubiquitous and often parasitize higher vertebrates and invertebrates alike. Only a limited number of amoeba species are capable of infecting humans, and typically invade the intestine. Specifically, only Entamoebahistolyticarepresents a true human pathogen, which infects the gastrointestinal tract. A second gut pathogen, Dientamoeba fragilis, is commonly mistaken as an amoeba owing to its similar morphology under a light microscope. Indeed, D. fragilis was originally misclassified as an amoeba; however, modern methods have identified it as a nonflagellate trichomonad parasite. Interestingly, some free-living amoebas can cause opportunistic infections in humans, leading to eye infections, as well as various neurological, and cutaneous (skin) infections.
