Answer:
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. Amebae species can be found in all major eukaryotic lineages, including fungi, algae, and even animals.
Amoebae 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.
