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 third part of the cell theory definition states that all cells come from preexisting cells. This means that cells don’t just appear out of thin air (known as “spontaneous generation”). New cells are always made from current cells.

Detailed explanation-3: -Part Six: Preexisting Cells It took a third scientist, Rudolf Virchow, to prove that cells did indeed come from other cells. But the research he used to prove this actually came from a German Jewish scientist named Robert Remak!

Detailed explanation-4: -The generally accepted portions of the modern Cell Theory are as follows: The cell is the fundamental unit of structure and function in living things. All organisms are made up of one or more cells. Cells arise from other cells through cellular division.

Detailed explanation-5: -Later, Rudolf Virchow (VUR koh) said all cells come from cells that already exist. The observations made by these scientists, shown in the table below, became known as the cell theory.
