A Eukaryote refers to an organism containing cells with complex structures and enclosed within membranes. Medically known by the name of the taxon Eukarya or Eukaryota, a majority of eukaryotic cells comprise membrane-centric organelles like mitochondria, the Golgi apparatus, and chloroplasts. Species of large complex organisms signify eukaryotes, including plants, fungi and animals, even though most eukaryote species are protest microorganisms. The cell division would vary in eukaryotes from those in organisms with prokaryotes (without a nucleus), such as Bacteria and Archaea. A eukaryote indicates a small minority of all living things, while there are ten times more microbes in a human body than in human cells.
