Bacteria are single-celled prokaryotic organisms with a simple body design. Their structure includes layers such as the extramural layer, surface appendages like flagella and pili, cell envelop with a cell wall and cytoplasmic membrane, and cytoplasmic inclusions. The capsule and slime layer play es
