The Domain Bacteria Consists Of Organisms Which Are

Archaea bacteria and eukarya.

The domain bacteria consists of organisms which are. The three domains are the archaea the bacteria and the eukarya. 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 bacteria are also prokaryotic. Their domain consists of cells with bacterial rrna no nuclear membrane and whose membranes possess primarily diacyl glycerol diester lipids.

According to this system the tree of life consists of three domains. Like bacteria archaea are prokaryotic organisms and do not have a membrane bound nucleus. 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. Any microbe that has a nucleus is a eukaryote.

This archaea domain contains single celled organisms. Because they are very similar to bacteria in appearance they were originally mistaken for bacteria. Any prokaryotic no nucleus microscopic organism that is self sufficient and recognized as alive is a bacterium. All life that has a cell nucleus and eukaryotic membrane bound organelles is included in eukarya.

The first two are all prokaryotic microorganisms or mostly single celled organisms whose cells have no nucleus.
