Which of the following statements is NOT part of the "Cell Theory"?
a
Cell is the basic structural and functional unit of life.
b
All cells arise from preexisting cells.
c
All cells arise spontaneously.
d
All living things or organisms are made of cells.
c
All cells arise spontaneously.
This statement is NOT part of the Cell Theory. The correct version aligned with the Cell Theory is that all cells come from pre-existing cells, not spontaneously. This aspect of the theory was proposed by Rudolf Virchow in 1855, who famously stated "Omnis cellula e cellula," meaning "every cell from a cell." The idea of spontaneous generation, where living organisms could arise from non-living matter, was a widespread belief before it was disproved through experiments by scientists such as Louis Pasteur.
