Prokaryotic Cell: Bacteria

A prokaryote is a single-celled organism without a membrane-bound nucleus or other organelles. All of the cell’s components are enclosed by its cell membrane. With some exceptions, a prokaryotic cell generally consists of a flagellum to aid in movement, a cell membrane, a cell wall to provide shape, cytoplasm, ribosomes and a nucleoid.
