The Domain Bacteria Consists Of Organisms Which Are

Any microbe that has a nucleus is a eukaryote.

The domain bacteria consists of organisms which are. The new domain names are bacteria archaea and eukarya where eukarya consists of organisms whose cells have a nucleus. Their domain consists of cells with bacterial rrna no nuclear membrane and whose membranes possess primarily diacyl glycerol diester lipids. Any prokaryotic no nucleus microscopic organism that is self sufficient and recognized as alive is a bacterium.

The bacteria are also prokaryotic. Bacteria can also fall into the subdomain archaebacteria generally these are bacteria that don t cause disease and eat inorganic stuff like sulfur or nitrogen for fuel. On the tree of life cells of the domain archaea are situated between the cells of bacteria and those of the eukarya which include multicellular organisms and higher animals.

The three domains are the archaea the bacteria and the eukarya. Archaea bacteria and eukarya. This archaea domain contains single celled organisms.

The first two are all prokaryotic microorganisms or mostly single celled organisms whose cells have no nucleus. Because they are very similar to bacteria in appearance they were originally mistaken for bacteria. According to this system the tree of life consists of three domains.

Organisms can be classified into one of three domains based on differences in the sequences of nucleotides in the cell s ribosomal rnas rrna the cell s membrane lipid structure and its sensitivity to antibiotics.
