Cells with cell chemicals and genetic material having no defined organelles and are all enclosed within a cell wall are called prokaryotes. Organisms in this group are small in size and are mainly bacteria. Ribosomes in these small cells are also small and ‘free floating’. DNA in prokaryotic cells is in the form of a circular strand and not as a chromosome.
