Detailed explanation-1: -It states that: All living organisms are made up of cells. Cells are the smallest units in a living organism that can perform all the functions of life. Rudolf Virchow in 1858 said “Omnis cellula-e-cellula", which means that all cells arise from the pre-existing cells only.
Detailed explanation-2: -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-3: -All living cells arise from pre-existing cells by division. The cell is the fundamental unit of structure and function in all living organisms. The activity of an organism depends on the total activity of independent cells. Energy flow (metabolism and biochemistry) occurs within cells.
