2. The Ultrastructure Of A Typical Bacterial Cell By Luke Jones

3. The Bacterial Cell This is a diagram of a typical bacterial cell, displaying all of its organelle.

4. The Bacterial Cell This is what a bacterial cell looks like under an electron microscope.

5. Next- The Organelle and their functions P.T.O

6. Bacterial Cell Wall Made from the Glycoprotein murein. Made from the Glycoprotein murein. Its purpose is to provide the cell with strength and rigidity. Its purpose is to provide the cell with strength and rigidity. It is permeable to solutes. It is permeable to solutes.

7. Cell Membrane This is made from phospholipids, proteins and carbohydrates, forming a fluid-mosaic. This is made from phospholipids, proteins and carbohydrates, forming a fluid-mosaic. It surrounds the bacteria and is its most important organelle. It surrounds the bacteria and is its most important organelle. It is controls the movement of substances in and out of the cell. It is controls the movement of substances in and out of the cell.

8. Genetic material The prokaryotic Bacterial cell has no nucleus. The prokaryotic Bacterial cell has no nucleus. Its genetic material and D.NA are contained in a nucleoid. Its genetic material and D.NA are contained in a nucleoid.

9. Ribosomes These are the smallest and most numerous of cell organelle. These are the smallest and most numerous of cell organelle. Their purpose is protein synthesis for the cells own use. Their purpose is protein synthesis for the cells own use. They consist of protein and RNA. They consist of protein and RNA. They are located either free in the cytoplasm of attached to the RER. They are located either free in the cytoplasm of attached to the RER.

10. Flagellum This is a rigid rotating tail. This is a rigid rotating tail. Its purpose is to propel the cell. Its purpose is to propel the cell. Clockwise rotation is what propels the cell forward, anticlockwise rotation causes a chaotic spin. Clockwise rotation is what propels the cell forward, anticlockwise rotation causes a chaotic spin. The rotation is powered by a H+ gradient across the cell membrane. The rotation is powered by a H+ gradient across the cell membrane.

11. Plasmid A plasmid is a small circle of DNA. A plasmid is a small circle of DNA. Bacterial cells have a number of plasmids. Bacterial cells have a number of plasmids. Plasmids are used to exchange DNA between bacterial cells. Plasmids are used to exchange DNA between bacterial cells.

12. Capsule This is a kind of slime layer covering the outside of the cell wall. This is a kind of slime layer covering the outside of the cell wall. It is composed of a thick polysaccharide. It is composed of a thick polysaccharide. It is used to stick cells together and as a food reserve. It is used to stick cells together and as a food reserve. It is also there to protect the cell from desiccation, and from chemicals. It is also there to protect the cell from desiccation, and from chemicals.
