An alternative spelling of eukaryote, an organism whose cells contain a nucleus and other membrane-bound structures.
From Greek 'eu' (true/good) + 'karyon' (nucleus), meaning 'true nucleus.' This variant spelling emerged alongside eukaryote in 20th-century biology, though eukaryote became the standard.
You are a eucaryote, along with every plant, animal, and mushroom—but bacteria are not, because their cells lack a nucleus to organize their DNA!
