Generally, all cells must have membranes, so yes they do.
Eukaryotes are believed to have evolved from a symbiotic relationship between an ancient archaebacterium and a eubacterium. This theory is supported by similarities in their genetic sequences, membrane structure, and other cellular processes. As a result, eukaryotes share more genetic and structural similarities with archaebacteria than eubacteria.
eubacteria because they are the most common prokaryotes. if something was an older form it would be more common because its been around for a long time.
it is a membrane. a membrane of a chloroplast.
No, the outer membrane of a chloroplast is not continuous with the thylakoid membrane. The outer membrane surrounds the entire chloroplast, while the thylakoid membrane is an internal membrane system within the chloroplast that contains the pigments and protein complexes necessary for photosynthesis.
the cell membrane
An archaebacterium is a primitive bacterium-like organism in the kingdom Archaea.
yea they are
metanogens
yes they are
Archaebacterium refers to micro-organisms which are similar to bacterial but have a different molecular structure. They are believed to be an intermediary between eukaryotes and bacteria.
Yes of course they have.Ribosomes are almost in every cell
Yes they are prokariyotic organisms.They are early cells on earth
Archaebacteria usually lack cholesterol as a fluidity barrier.

Come again, please? An archaebacterium is a unicellular prokaryote. It doesn't even have a nucleus, let alone any organ systems!
eubacteria because they are the most common prokaryotes. if something was an older form it would be more common because its been around for a long time.
Protist is a unicellular eukaryote, whereas algae can be unicellular or multicellular. Bacteria and archaebacteria are both prokaryotes and are typically unicellular organisms.
