Detailed explanation-1: -New cells are created from existing cells through a process referred to as the cell cycle. One cell can make a copy of itself and form two new daughter cells. There are two major tasks that have to happen every cell cycle. First, cells have to make an exact copy of their DNA.
Detailed explanation-2: -Two cells are formed from one cell through the process of cell division. In cell division, the DNA within a cell is replicated. The two copies of the DNA are then separated into two different cell nuclei. The cell then splits into two pieces, each piece containing its own set of DNA.
Detailed explanation-3: -New cells generate from pre-existing cells. Rudolf Virchow (1985) first explained that cells divide and new cells are formed from pre-existing cells (omnis cellula-e cellula). He modified the hypothesis of Schleiden and Schwann to give cell theory a final shape.
