| Question | Answer |
| Plasma Membrane | Holds all of the intracellular material and regulates the movement of materials into and out of the cell. |
| Cytoplasm | This is the gel-like fluid that the cell is filled with, inside the plasma membrane; liquid with all of the cellular organelles suspended within. |
| Cytoskeleton | This scaffolding provides structural support to the cell and plays a role in cell division. |
| Ribosomes | Ribosomes are the tiny protein-making machines that carry out the genetic instructions of the cell. |
| Cell Wall | Prevents them from bursting in a hypotonic environment |
| Glycocalyx | Is a layer outside of the cell wall, and present in some bacteria. |
| Cell Extensions | There are several different types of cell extensions associated with bacteria, all a made of delicate protein strands. Bacterial cell extensions include: |
| flagella | Long whip-like extensions that help bacteria move about the environment |
| Axial filaments (endoflagella) | flagella that are wrapped around corkscrew-shaped bacteria, and which move in waves that make the bacteria spin |
| fimbriae | Allow bacteria to adhere to target host cells, and play a major role in bacterial virulence |
| conjugation pili | Used to transfer plasmids from donor to recipient bacteria |
| Nucleoid | Contains the genome—the main genetic material (DNA) of the cell. |
| Plasmids | A plasmid is a non-essential piece of DNA that confers an advantage to the bacteria |
