Prokaryotic Cell Structure . In general speech , Bacteria cell structure can be divided into 3 parts: external (appendages & coverings), cell envelope (cell wall and membranes), and internal organelles. The external structures of a bacterial cell include appendages for movement (flagella) and adhesion (pili, fimbriae, and glycocalyx) to surfaces.
