Is a simple cell a bacteria or a virus?

Thanks for answering! ♥

Is a simple cell a bacteria or a virus?
It depends on what you mean by a "simple cell". Most bacteria are cells or chains or colonies of cells but not all cells are bacteria. E.G. skin cells, muscle cells (not simple), brain cells. A virus is not considered a cell. It lacks the complicated machinery of a living cell that allows it to multiply (among other things). That's why a virus needs to get into a living cell to use the cell's machinery to make copies of itself. Different kinds of viruses do this differently but the idea is basically the same. Invade a cell, take over it's production tools, and make copies of itself. Libby T.
Reply:Bacteria. Viruses aren't really cells at all.
Reply:Viruses are not cellular in nature. They are composed of organic material, but they fall short of designation as cellular as they have the inability to duplicate their genetic material and require a host cell to do so.
Reply:A simple cell is just that - a cell.

This excludes viruses, since viruses are just genetic material (DNA, RNA or both) coated with protein.

Other than that, a simple cell can be any living thing you can name - human cells, plant cells, animal cells, bacteria cells etc.
