| I: | The outermost layer of the cell envelope is called as the glycocalyx which may be present as a loose sheath called the slime layer or a thick and tough capsule. |
| II: | The cell wall determines the shape of the cell and provides a strong structural support to prevent the bacterium from bursting or collapsing. |
