Humans are eukaryotes, as are oak trees, mushrooms, and amoebas. Many, but not all, eukaryotic cells contain additional membrane-bounded organelles (e.g., mitochondria, chloroplast, Golgi bodies, etc.). The name eukaryote is derived from Greek eu-, meaning true, and karyon, denoting nucleus.
Eukaryotes can be single-celled or multicelled, such as you, me, plants, fungi, and insects. Bacteria are an example of prokaryotes. Prokaryotic cells do not contain a nucleus or any other membrane-bound organelle.
