Single cells
one kind of archaebacteria is the methanogens
Archaebacteria do have cell walls, although not the same kind that plant cells have.
No, archaebacteria have simple cells lacking membrane-bound organelles found in eukaryotic cells. They are prokaryotic organisms with a simpler internal structure.
Archaebacteria is a domain of single-celled microorganisms with no cell nucleus or other organelles in their cells. The non-scientific name for Archaebacteria is Archaea.
Prokaryotes
Here are the 3 types of Archaebacteria Archaebacteria>>>>> 1. Methanogens 2. Halophiles 3. Thermoacidiophiles
Billy is a kind Archaebacteria who will go out of his way to help old ladies across the street.
Mammalian red blood cells have no nucleus. Bird and reptile red blood cells DO have a nucleusProkaryotes - bacterial cells (eubacteria and archaebacteria).
Archaebacteria
Eubacteria have prokaryotic cells. Eubacteria IS Kingdom Bacteria! The Eu- was there to distinguish it from Archaebacteria when Archaebacteria were in the same kingdom as Eubacteria and not in its own kingdom of Archae, as they are now. (The old kingdom that contained both Eubacteria and Archaebacteria was called Kingdom Monera)
One cell These are all single cell organisms.
The two kingdoms that contain all prokaryotic organisms are Bacteria and Archaea. These organisms lack a true nucleus and other membrane-bound organelles in their cells.
