What facts did redis spallanzanis and pasteurs experiments establish?
Spallanzani's experiments demonstrated that microorganisms did not spontaneously generate but instead came from existing microbes, as he showed that sealed flasks of broth remained sterile when not exposed to air. Later, Pasteur built on this by using swan-necked flasks, which allowed air in but prevented dust and microbes from contaminating the broth, further confirming that microbial life arose from pre-existing life. Together, their work established the principle of biogenesis, disproving the theory of spontaneous generation.
Why was pasteurs experiment better than spallanzanis?
Pasteur's experiment demonstrating spontaneous generation was considered better because he designed a more controlled experiment with swan-necked flasks that allowed air in but prevented microbes from entering. This disproved the theory of spontaneous generation more conclusively than Spallanzani's experiment which critics argued could have been affected by lack of oxygen.

What did people think about cells before Pasteurs experiments with beef broth and s shaped tubing?
Cells came from nonliving things.or Cells could generate spontaneously.
Louis pasteurs experiments brought to an end the theory of what generation?
Louis Pasteur's experiments brought an end to the theory of spontaneous generation, which proposed that living organisms could arise from non-living matter. Pasteur's work demonstrated that microorganisms do not spontaneously generate but instead come from existing cells.

What was shown by both Redis and Pasteurs experiments?
Both Redis and Pasteur's experiments demonstrated that microorganisms do not spontaneously generate but rather arise from existing microbes in the environment. Redis used a series of jars with meat and gauze to show that maggots only appeared when flies could access the meat, while Pasteur's swan-neck flask experiments confirmed that sterilized broth remained free of microbial growth unless exposed to contaminants in the air. These findings collectively supported the germ theory of disease and refuted the idea of spontaneous generation.
