a virus
A virus is a particle with DNA but no nucleus or cell wall.
A single cell virus particle is called a virion. It consists of genetic material enclosed in a protein coat.
A virus is a microscopic particle that invades a cell, takes over its machinery to replicate, and ultimately destroys the cell as part of its life cycle.

The cell Wall
It has to be able to hijack a living cell, enter the cell though matching protein docking stations. Then it enters with just its' DNA or RNA (one or the other). It makes the host cell make just virus parts and assemble them. When the cell is full, it breaks open. They cell can not replace its' own parts so the membrane falls apart.
Virus cannot replicate themselves. They should enter a living cell
The answer to this question is a virus!a virus is what causes you to get a flu and other sicknesses. Remember, a virus is NOT A LIVING ORGANISM! There for, it needs a host cell to reproduce and get nutrients.
at first i was crying but then it just hit me it was a stupied virus
A virus is a microscopic being that can invade and destroy a cell. Viruses have some, but not all, of the characteristics of living things.
