Question

Do any other microbial groups besides bacteria have prokaryotic cells? if so, what are they?

Answer 1

In 1977, Carl Woese proposed dividing prokaryotes into the Bacteria and Archaea (originally Eubacteria and Archaebacteria) because of the major differences in the structure and genetics between the two groups of organisms.

Archaea are a newly appointed domain of life. These organisms were originally thought to live only in inhospitable conditions such as extremes of temperature, pH, and radiation but have since been found in all types of habitats.

Answer 2

archeae!

Answer 3

The only organisms that have prokaryotic cells are bacteria.  The two bacterial kingdoms contain all of the prokaryotic cells.  All other kingdoms contain Eukaryotic cells.  So if you see a prokaryote... call it a bacterium!

Answer 4

i think there are, but they are VERY minimal. typically, when the reference is to prokaryotic cells, it means bacteria. i hope someone can fully answer this question for you..

Answer 5

"bacteria" should really be split into two different groups, which are as different from each other at a deep genetic level as they are from eukaryotes.

Most of the bacteria that you would learn about in a microbiology class are "eubacteria" or "true bacteria.  e.coli, B.subtilis, s.aureus, m.tuberculosis, t.palidum, etc.

"Archaebacteria" is the other family.  Their best known members are extremophiles, which is a general name for a bacterium that lives is some really difficult environment, like a superheated spring, or a super acidic undergroundd lake.

Some people think that all extremophiles are Archae, or that all archae are extremophiles, but this isn't true.

Answer 6

Yes.  The highest order of life is classified as a domain, of which there are three of: Domain Bacteria, Domain Eukarya, and Domain Archae.  Domain Eukarya is made up of all living organisms that have eukaryotic cells, which are cells that contain a nucleus and membrane-bound organelles.  Domain Bacteria and Domain Archae are made up of all living organisms containing prokaryotic cells, which are cells that do not have a nucleus or membrane-bound organelles.  To focus your answer, Domain Archae is what you are looking for.  This domain consists of prokaryotic "ancient bacteria."  These organisms are nature's prehistoric extremophiles; they live in exotic places like ocean vents and volcanoes, places where no other organism could even hope to live.  They can withstand inconceivable conditions, like highly acidic and basic environments, no sunlight, high and low temperatures, and radiation.  Archae can even reconstruct their own DNA!!  And although they are prokaryotic, these mysterious wonders are just as closely related to humans as they are with their prokaryotic counterparts.
