Detailed explanation-1: -The third part, which asserts that cells come from preexisting cells that have multiplied, was described by Rudolf Virchow in 1858, when he stated omnis cellula e cellula (all cells come from cells).
Detailed explanation-2: -The generally accepted parts of modern cell theory include: All known living things are made up of one or more cells. All living cells arise from pre-existing cells by division. The cell is the fundamental unit of structure and function in all living organisms.
Detailed explanation-3: -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-4: -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-5: -1) All organisms are made of cells. 2) All existing cells are produced by other living cells. 2) All existing cells are produced by other living cells. 3) The cell is the most basic unit of life.
