WebArchaea and Bacteria generally have a single circular chromosome– a piece of circular, double-stranded DNA located in an area of the cell called the nucleoid. In contrast, many eukaryotes have multiple, linear chromosomes. Archaea and Bacteria reproduce through fission, a process where an individual cell reproduces its single chromosome and ... WebSection Summary. Prokaryotes are single-celled organisms of the domains Bacteria and Archaea. All prokaryotes have plasma membranes, cytoplasm, ribosomes, and DNA that is not membrane-bound. Most have peptidoglycan cell walls and many have polysaccharide capsules. Prokaryotic cells range in diameter from 0.1 to 5.0 μm.
Web17 jan. 2024 · The word “amoeba” describes a wide variety of single-celled organisms that look and behave a certain way. Some organisms are amoebas for only part of their lives.

WebExplanation of correct option: The organisms that are single-celled, and lack a nucleus, nuclear membrane, and other prominent cellular organelles are called prokaryotes. They are divided into two groups: archaeobacteria and bacteria. Blue-green alga is an example of archaeobacteria. Explanation of incorrect options: Option B: Amoeba do not have cell walls, which allows for free movement. Amoeba move and feed by using pseudopods, which are bulges of cytoplasm formed by the coordinated action of actin microfilaments pushing out the plasma membrane that surrounds the cell. The appearance and internal structure of pseudopods are used to distinguish groups of amoebae from one another. Amoebozoan specie…
WebProkaryotes are further divided into two main kinds of organisms: bacteria and archaea. Some examples of prokaryotic organisms include the common bacteria E. coli, the archaea M. Smithii which helps humans break down polysaccharides in the intestines, and Deinococcus radiodurans, a species of bacteria known for its extreme radiation resistance.
