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. WebMar 6, 2024 · Note that not all prokaryotic cells have a cell wall, and not all eukaryotic cells have flagella or cilia. Additionally, these generalizations have some exceptions, such as bacteria with membrane-bound compartments or eukaryotic cells lacking a true nucleus (such as red blood cells).
