| Question | Answer |
| what is flagellum and what is it’s function? | They are long thread like projections hanging from the cell membrane or capsule providing motility. |
| what is a spore and what is it’s function? | - Spores are protective coating that covers the cell and bacteria so nothing can enter or leave |
| ) What genera of bacteria forms spores? And why are they dangerous - | Only rod shaped bacillus bacteria form spores and dangerous because they cause toxins and are hard to kill. |
| What does pathogenic bacterium have that nonpathogenic bacterium usually does not have? | Pathogenic bacteria are encapsulated and nonpathogenic is not. |
