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: -As Rudolph Virchow said previously in 1858, omnis cellula e cellula, which is Latin for “all cells arise from other cells."
Detailed explanation-3: -All cells come from pre-existing cells by cell division. Schwann also proposed “Free Cell Formation” or spontaneous generation of cells-this was before Pasteur’s definitive experiments. Modern Cell Theory Also States: Life’s chemical processes, such as metabolism, occur inside of cells.
Detailed explanation-4: -All cells arise from other cells DNA replication occurs during the interphase of the cell cycle. Mitosis is the part of the cell cycle in which a eukaryotic cell divides to produce two daughter cells, each with the identical copies of DNA produced by the parent cell during DNA replication.
