Detailed explanation-1: -When cells become damaged or die the body makes new cells to replace them. This process is called cell division. One cell doubles by dividing into two. Two cells become four and so on.
Detailed explanation-2: -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-3: -Scientists once thought that life spontaneously arose from nonliving things. Thanks to experimentation and the invention of the microscope, it is now known that life comes from preexisting life and that cells come from preexisting cells.
