They both found out the the theory was wrong. Redi's experiment was to have two jars, one uncovered and the other one covered by a cloth. The next day, the flies came to the opened one and layed eggs on it. No maggots came on the covered one. They both proved it wrong.

How Louis Pasteur disprove the theory of abiogenesis?
By actual experimentation, the great French scientist Louis Pasteur disproved this false theory of spontaneous generation.Abiogenesis is not the same as spontaneous generation! Spontaneous generation actually posits that full born organisms come from miasma and the like. Abiogenesis posits by hypothesis that life is of simpler organic constituents.Pasteur then entered a contest sponsored by The French Academy of Sciences to disprove the theory of spontaneous generation. Similar to Spallanzani's experiments, Pasteur experiment, pictured in Figure 1-6, used heat to kill the microbes, but left the end of the flask open to the air. In a simple, but brilliant modification, the neck of the flask was heated to melting and drawn out into a long S-shaped curve, preventing the dust particles and their load of microbes from ever reaching the flask. After prolonged incubation the flasks remained free of life and ended the debate for most scientists.Source: [related links]Abiogensis is not the same as spontaneous generation.Pasteur's law only disproved the (then current) idea that life forms such as mice, maggots, and bacteria can appear fully formed. It does not say that very primitive life cannot form from increasingly complex molecules.
Which of the following requirements was NOT necessary for Pasteur to disprove spontaneous generation?
Identifying Bacteria
What invention supported Louis Pasteur's research?
Louis pasteur reject abiogenesis theory and give biogenesis theory which state that life exist from pre existing life. He prove it by one of his famous experiment of S shape funnel broth experiment
What did Francesco Redi and Louis Pasteur demonstrate in their experiments?
Francesco Redi and Louis Pasteur, as well as Lazzaro Spallanzani and John Tyndall, all did scientific experiments (as opposed to philosophical writings) challenging the idea that life could quickly arise in the absence of any life from which other life could grow. This idea, formally dating back to the ancient Greeks, is called "spontaneous generation." The experiments of these four showed that spontaneous generation did not occur in situations that others thought it did. Like any good science controversy, other scientists did experiments that supported spontaneous generation, but Pasteur and Tyndall were able to do experiments that were rigorous enough to unambiguously disprove this idea.
Which theory did pasteur disprove by using boiled beef broth and a flask with s-shape tubing?
spontaneous generation
The experiments conducted by this scientist demonstrated the principle of biogenesis.?
The experiments conducted by the scientist Louis Pasteur demonstrated the principle of biogenesis.
How did the cattle plague contribute to people's acceptance of Pasteur's Germ Theory?
Louis Pasteur was able to convince others of his germ theory by performing extensive experiments. Through these experiments, he was able to disprove spontaneous generation and prove biogenesis.
Who were the two early scientists whose experiments helped disprove the idea of spontaneous generation?
Redi and Pasteur helped to disprove spontaneous generation.
How do the Redi Spallanzani and Pasteur experiments disprove the hypothesis?
they didnt
Who proved biogenesis?
Luis pasteur
Who was supplied proof for virchow's biogenesis?
louis pasteur
What scientist used flasks to support the theory of biogenesis?
Louis pasteur was the one to support th theory of biogenesis.
Who originated theory of biogenesis?
The Law of Biogenesis, attributed to Louis Pasteur, states that life arises from pre-existing life, not from nonliving material.
What did lazzaro spallanzani invented?
His research of biogenesis paved the way for the investigations of Louis Pasteur

What scientist responsible for disproving the theory of spontaneous generation?
Francesco Redi, in 1668, showed that abiogenesis of maggots did not occur, and further experiments by Lazzaro Spallanzani (1768) and Louis Pasteur (1861) showed that many of the lifeforms thought "created" were those already invisibly present in the air or in other materials.
What is the theory that today organisms evolved from past organisms?
This theory is called biogenesis. It was formulated by Louis Pasteur.
