Concepts Prokaryotes are small and simple in structure when compared with eukaryotes,yet they often have characteristic shape and size. Prokaryotic genetic material is located in an area called the nucleoid and is not enclosed by a membrane. The prokaryotic cell wall almost always has peptidoglycan and is chemically and morphologically complex
Concepts • Prokaryotes are small and simple in structure when compared with eukaryotes , yet they often have characteristic shape and size. • Prokaryotic genetic material is located in an area called the nucleoid and is not enclosed by a membrane. • The prokaryotic cell wall almost always has peptidoglycan and is chemically and morphologically complex

A procaryotic cell A eucaryotic cell 2.1 Overview of Cell Structure
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 3.Their cell wall almost always contain the complex polysaccharide peptidoglycan 4.They are very small!!
