3. Their cell wall almost always contain the complex polysaccharide peptidoglycan The prokaryotic cell 1. Their genetic material (DNA) is not enclosed within a membrane and they lack other membrane – bounded organelles 2. Their DNA is not associated with histidine 4. They are very small!!

Size: Most bacteria fall within a range from 0.2 to 2.0 um in diameter and from 2 to 8 um in length A rod-shaped prokaryote is typically about 1-5 micrometers (μm) long and about 1 μm wide Microorganisms in general are very small and are completely invisible to the naked eye. A cyanobacterium 8 x 50 um
