Imagine a tiny virus is like a sneaky thief who can’t do anything on its own, it needs to steal tools from a bacterium, which is more like a strong, independent worker. The virus tricks the bacterium into making copies of itself, while bacteria can multiply all by themselves.
Examples
- A virus is like a thief who needs a bacterium’s tools to multiply, while bacteria can make copies of themselves without help.
- Viruses are tiny invaders that need a host cell, whereas bacteria can grow by themselves in the soil or your gut.
- When you get sick from a cold, it's a virus; if it's a bacterial infection like strep throat, it’s a different kind of germ.
