Is eubacteria motile or non-motile?
Bacteria is the plural form of bacterium which is a unicellular prokaryotic microorganism that usually multiplies by cell division and has a cell wall that provides a constancy of form; they may be aerobic or anaerobic, motile or nonmotile, and free-living, saprophytic, commensal, parasitic, or pathogenic
Both archeabacteria and eubacteria are members of the kingdom monera (bacteria). These group of organisms are all single celled and don't even have a cell nucleus. They therefore totally lack motile functions of their own but are carried around by their environment such as being washed down a stream or similar.
