Eukaryote

Eukaryotes are organisms whose cells have a nucleus enclosed by a nuclear membrane. This group includes higher plants, animals, and some microorganisms, such as molds and yeasts. Eukaryotic cells contain various membrane-bound organelles, which give them a high degree of functionality and complexity. In contrast, prokaryotes are organisms whose cells lack a nuclear membrane, and they are mainly bacteria and archaea. The existence of eukaryotes has played an important role in the evolution of the diversity of life on Earth.
