pro·kar·y·ote

also pro·car·y·ote  (prō-kăr′ē-ōt′)
n.
Any of various microorganisms of the domains Archaea and Bacteria, characterized by the absence of a distinct membrane-bound nucleus and membrane-bound organelles and by the simultaneous occurrence of DNA transcription and protein synthesis at the same site, in contrast to eukaryotes. Also called moneran.

[French procaryote : Greek pro-, before; see pro-2 + Greek karuōtos, having nuts (from karuon, nut; see karyo-).]

procaryote

n
(Biology) any organism having cells in each of which the genetic material is in a single DNA chain, not enclosed in a nucleus. Bacteria and archaeans are prokaryotes. Compare eukaryote

pro•kar•y•ote

or pro•car•y•ote

(proʊˈkær iˌoʊt, -i ət)

n.
any one-celled organism that lacks a distinct membrane-bound nucleus and has its genetic material in the form of a continuous strand forming loops or coils: characteristic of monerans. Compare eukaryote.

pro·kar·y·ote

(prō-kăr′ē-ōt′)
Any of a wide variety of one-celled organisms that lack a distinct cell nucleus or other structures bound by a membrane and that have DNA that is not organized into chromosomes. Prokaryotes reproduce asexually, are the most primitive and ancient known forms of life, and include the bacteria and blue-green algae. Prokaryotes are grouped as a separate kingdom in taxonomy. Also called moneran. Compare eukaryote. See Table at taxonomy.

Prokarya would include two kingdoms: Eubacteria and Archaebacteria
Despite their obscurity, the archaea constitute a third kingdom of life, alongside the prokarya, cells like bacteria that have no nucleus, and the eukarya, organisms with nucleated cells, which include all plants and animals.
