How did Louis Pasteur's experiment prove the cell theory and disprove the theory of spontaneous generation?

Answer 1

In 1668, Italian physician Francesco Redi first performed tests with rotting meat that showed that maggots did not form spontaneously as was previously thought. It suggested that living things could only be formed from living things of the same type.

Louis Pasteur in 1861 improved upon the experiments of John Needham, who in 1745 had suggested that living things could form despite sterilization of the medium. Pasteur boiled solutions in beakers that had necks shaped like an S, so that airborne microorganisms could not reach the solution past the neck. Mold did not appear in the unexposed liquid that was boiled, but did in the solution that was exposed to bacteria from the air.

Answer 2

Louis Pasteur's experiment involved boiling broth in a flask with a curved neck that prevented dust particles from entering. He found that the broth remained sterile unless the neck was broken, allowing contaminants to enter. This demonstrated that microorganisms come from pre-existing cells, supporting the cell theory and disproving the idea of spontaneous generation that living organisms can arise from non-living matter.
