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.
