Here's how:
* The Experiment: Pasteur designed a series of experiments using swan-necked flasks. These flasks had a long, curved neck that allowed air to enter but prevented dust and microorganisms from reaching the broth inside.
* The Results: When the broth in the swan-necked flasks was boiled, it remained sterile for extended periods. However, when the necks were broken, allowing dust and microorganisms to enter, the broth quickly became cloudy with microbial growth.
* The Conclusion: Pasteur's experiments demonstrated that life does not spontaneously arise from non-living matter. Instead, it arises from pre-existing life. This supported the theory of biogenesis, which states that living organisms can only arise from other living organisms.
Pasteur's experiments were a major turning point in our understanding of how life begins and played a significant role in disproving the theory of spontaneous generation.
