When cells are damaged, new cells are created by cell a process called cell division. How does the cell theory support this fact?
It states that all cells have a nucleus which divides.
It states that all living things are made up of one or more cells.
It states that cells come from previously existing cells.
It states that the basic units of structure and function are cells.
