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.
The presence of a nucleus gives eukaryotes their name, which comes from the Greek ÎµÏ (eu, well) and ÎºÎ¬ÏÏÎ¿Î½ (karyon, nut or kernel). Eukaryotic cells also contain other membrane-bound organelles such as mitochondria and the Golgi apparatus. In addition, plants and algae contain chloroplasts. Eukaryotic organisms may be unicellular, or multicellular. Only eukaryotes have many kinds of tissue made up of different cell types.
