Prokaryotic cells do not have a nucleus surrounded by a complex nuclear membrane, where single, circular chromosome situated in a nucleoid. (Pro: primitive; Karyon: nucleus).
Prokaryotic cell - Bacteria
Eukaryotic cells have a nuclear membrane that surrounds the nucleus where the well defined rod-shaped chromosome are present. (Eu: True or well; Karyon: nucleus). Eukaryotic cells are further classified into plant cell and animal cell.
Eukaryotic cell - Animal cell
