Part of speech: noun

Definitions

1. A type of organism that lacks a defined nucleus and membrane-bound organelles, representing a basic form of cellular life

Etymology: "Akaryote" is a rare variant. It combines the Greek privative "a-", meaning "without", with "karyon", a Greek word for a nut or kernel. Biologists applied "karyon" to the nucleus, the dense inner body they saw inside cells, so the compound describes a cell without one. The term in standard use is "prokaryote", where "pro-" means "before", a name that reflects the idea that these cells came before cells with nuclei. Its counterpart, "eukaryote", uses "eu-", meaning "well" or "true", for cells that have a true nucleus. Prokaryotes include bacteria and archaea.
