Louis Pasteur conducted the swan-neck flask experiment to demonstrate that there was no spontaneous generation of life. He showed that when broth was heated and sealed in a flask with a curved neck, no microorganisms grew, proving that life did not spontaneously arise from non-living matter.

Pasteur's experiment on spontaneous generation showed that microorganisms do not arise spontaneously but are introduced into broths from external sources. Spallanzani's experiment involved boiling nutrient broth in sealed flasks to sterilize it, then observing that no microorganisms grew unless air was allowed to enter the flask, suggesting that microbes were not generated spontaneously but entered from the air.

Louis Pasteur is the scientist who demonstrated that microorganisms do not arise from spontaneous generation through his famous experiments with swan-necked flasks in the 19th century.
Louis Pasteur disproved the theory of spontaneous generation, which suggested that living organisms could arise from non-living matter. Through his experiments with swan-necked flasks, Pasteur demonstrated that microorganisms in the air were responsible for contamination, rather than spontaneous generation.
The responding variable in Pasteur's experiment was the presence or absence of microorganisms in the broth after being exposed to different conditions, specifically the S-shaped flask that prevented airborne microorganisms from entering the broth. This variable helped Pasteur demonstrate that spontaneous generation of life does not occur.
yes he did
Redi and Pasteur helped to disprove spontaneous generation.
he set the foundation on which Louis Pasteur disproved spontaneous generation.

He wanted to disprove spontaneous generation; that micro organisms were not carried by air, but were deposited from dust.
Pasteur
Pasteur's experiment refuted the theory of spontaneous generation by demonstrating that microorganisms in broth were killed by heat and could only enter through the air. Spallanzani's experiment involved boiling broth in sealed flasks to prevent microorganism entry, concluding that the lack of spontaneous generation was due to the lack of vital force rather than the absence of air.
The experiments of Redi and Pasteur helped to demonstrate that all organisms come from other organisms. At the time, the prevailing theory was called "Spontaneous Generation" which assumed that organisms simply appeared. Both scientists delt with proving that, in the presence of oxygen, organisms did not grow if they were not exposed to microbe-containing air.
No, you need to do this. Go into your science book and read what it has on Pasteur. It is only a few paragraphs. Take the main idea of each and you have a summary of his experiment.
that non-living thing cant rising living thing and prove that spontaneous generation is wrong.
Louis Pasteur concluded from his experiment that spontaneous generation does not occur, and that microorganisms present in the air were responsible for the contamination of the broth. This observation led to the development of the germ theory of disease and revolutionized our understanding of infectious diseases.
