WebAlmost all prokaryotes, which include the bacteria and the archaea, have cell walls. Bacteria account for most prokaryotes and 90 percent have cells walls. These bacteria can be divided into gram-positive and gram-negative types based on the staining of the peptidoglycan in their cell walls. WebA prokaryote (/ p r oʊ ˈ k ær i oʊ t,-ə t /) is a single-celled organism that lacks a nucleus and other membrane-bound organelles. The word prokaryote comes from the Greek πρό (pro, 'before') and κάρυον (karyon, 'nut' or 'kernel'). In the two-empire system arising from the work of Édouard Chatton, prokaryotes were classified within the empire Prokaryota.
