Bacterial cell structure
Bacteria, despite their simplicity, contain a well-developed cell structure which is responsible for many of their unique biological structures. Many structural features are unique to bacteria and are not found among archaea or eukaryotes. Because of the simplicity of bacteria relative to larger organisms and the ease with which they can be manipulated experimentally, the cell structure of bacteria has been well studied, revealing many biochemical principles that have been subsequently applied to other organisms.
