Detailed explanation-1: -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.
Detailed explanation-2: -The principle of biogenesis states that all living organisms arise from a pre-existing living organism. The theory of biogenesis is attributed to Louis Pasteur. The theory states that life comes from pre-existing life, by means of reproduction.
Detailed explanation-3: -When this long-standing myth was finally dispelled in the mid-1800s, it became clear that all life must arise from pre-existing life — via a process of reproduction. If cells are the fundamental units of life, they too must have a reproductive mechanism that maintains the proper chromosome number in each cell.
