Eukaryotic cells: nuclear membrane present, nucleus (mass of dna surrounded by membrane, single celled or multicellular. When one organism lives inside of another : mitochondria used to be a separate bacteria cell, developed a symbiotic relationship with ancestral eukaryotic cell, ancestral cell ingested mitochondria, resulted in permanent evolutionary relationship.
