Answer:

Louis Pasteur

Explanation:

Louis Pasteur designed an  experiment in which he proved that life cannot generate or grow spontaneously. It needs some base for taking birth or rebirth.

For instance, in his experiments the flasks that were exposed to the dust have generated cloudy solution but the flask that were unbroken did not show any such sign. Thus , he proved that microbes appeared in broken flask because of the presence of dust.

Hence he showed that that organisms do not grow spontaneously in beef broth

Answer:

Louis Pasteur.

Explanation:

Louis Pasteur gave theory of spontaneous generation that states, life arose from non-living things. Pasteur disprove the theory of spontaneous generation by S-shaped tube experiment.

He used swan-neck shaped flasks (twisted necks) and filled the flasks with sterilized beef broth.  Due to twisted neck, entry of air was allowed to the flasks from outside, but not microorganisms.

In these sterilized flasks, microorganisms could not grow as entry of airborne microbes was prevented. But if the necks of flasks were broken,  growth of microorganisms entered into flasks and showed growth.

Thus, Louis Pasteur showed that microorganisms do not grow spontaneously in flasks with beef broth.
