Q:

How do eubacteria and archaebacteria differ?

A:

Quick Answer

Eubacteria and archaebacteria have several key biological differences, primarily in the membrane and wall structure of their cells. Eubacteria and archaebacteria have similar general cell structures, but the composition and layout of those cellular components is remarkably different. Archae, like eubacteria, lack interior membranes and use flagella to maneuver but have cell walls comprised of peptidoglycan

Full Answer

In addition to differing in their cell structures, eubacteria and archaea have different flagella. The flagella found in archaeabacteria derives from the bacterial type IV pili variety, while the flagella of eubacteria comes from the type III secretion system. Eubacteria flagellum is thin and stalk-like in appearance, with a hollow center and comprised of tiny subunits. Those found in archaea, by contrast, are shorter, broader and attached directly to the base. Both organisms reproduce asexually through the process of binary fission, followed by budding and fragmentation. Eubacteria, however, go on to form spores that can remain dormant for several years; this trait is not expressed by archaea. Eubacteria and archaeabacteria share several overlapping habitats, such as hot springs, within the crust of the earth’s surface, and in the bodies of plants, animals and humans. Both are adapted to life in harsh conditions, but eubacteria prefer moist climates, while archaeabacteria enjoy hot and dry locations

  • Q:

    What are specific types of eubacteria?

    A:

    Eubacteria fall into four primary categories, which are gram-positive eubacteria, proteobacteria, cyanobacteria and spirochetes. Eubacteria are much more common than archaebacteria, which are closely related members of the prokaryote division. Eubacteria live in many areas around the world, including some of the most extreme and inhospitable environments.

  • Q:

    What are Eubacteria organisms?

    A:

    Eubacteria organisms, also referred to as true bacteria, are organisms that are complex yet singled-celled. An example of bacteria in the Eubacteria kingdom are Streptococci, the bacterium responsible for strep throat. Some eubacteria produce food, such as yogurt, and help create vitamins. Other organisms in this kingdom include blue-green algae and actinobacteria.

    What is the mode of nutrition for the kingdom Eubacteria?

    A:

    There are four modes of nutrition for the kingdom Eubacteria: photoautotrophs, chemoautotrophs, photoheterotrophs and chemoheterotrophs. Each of these has a different combination of ways that they obtain energy and carbon.
