| − | The '''cell''' is the smallest unit of life capable of independently reproducing itself. A bacterium is a simple cell without a [[nucleus]] to protect its genetic information. A virus requires structures in a cell's [[cytoplasm]] to assemble copies of itself. There is no consensus on the number of cells in a human body, the number ranges from 10 to 100 trillion cells. | + | The '''cell''' is the smallest unit of life capable of independently reproducing itself.
