prokaryoten.

Brit.

/prəʊˈkarɪəʊt/,

/prəʊˈkarɪɒt/, U.S.

/proʊˈkɛriˌoʊt/

Forms: 1900s– procaryote, 1900s– prokaryote.

Origin: A borrowing from French. Etymon: French procaryote.

Etymology: < French procaryote (É. Chatton 1925, in Ann. des sci. nat.: Zool. 8 76) < pro- pro- prefix² + ancient Greek κάρυον nut, kernel (see -karyon comb. form) + -ώτης -ote suffix. Compare earlier prokaryon n., prokaryotic adj., and eukaryote n.

Biology.

A prokaryotic organism. Contrasted with eukaryote.Prokaryotes are often classified in their own kingdom ( Monera or Prokaryota), but they are now more usually divided between the two domains Archaea (see Archaea n.) and Bacteria.
