Cell Division of Course!
So how are new cells formed?
The cell is a basic structural and functional unit of all living things, ranging from tiny bacteria to whale dicks and even humans. All cells must divide to reproduce. For single-celled organisms, cell replication is necessary for reproduction. For multi-cellular organisms, cell replication is necessary for growth, reproduction and for maintaining the body by replacing dying cells.
In large, complex organisms, such as mammals, cells divide and die in a cycle that keeps the tissues of the organism rejuvenated. The process is called the cell division and the complete cycle of cell division is called a cell cycle.
