Explanation:
Detailed explanation-1: -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: -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.
