eukaryote cultural definition

An organism whose cells contain a nucleus. All multicelled organisms are eukaryotes, as is one superkingdom of single-celled organisms. Eukaryotes also have organelles enclosed by membranes. (Compare prokaryote.)

• Eukaryotes evolved in a process in which one early prokaryote consumed another, forming a more complex structure.
• The word eukaryote comes from the Greek for “true nucleus.”
