Francesco Redi was the first person to question the validity of spontaneous generation. He was able to disprove the theory by showing that maggots came from fly eggs.

What did Pasteur's conclude from his experiment?

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.


How pasteur's experiment supported the cell theory and failed to support the theory to spontaneous generation?

Louis Pasteur's experiment with the swan-necked flasks demonstrated that microorganisms in the air could contaminate the broth only if they were given access, proving that spontaneous generation of microorganisms did not occur. This supported the cell theory by showing that cells only arise from pre-existing cells, not from non-living matter.


What were the experiments that were used to explain the concept of spontaneous generation?

Francesco Redi - One of the first to disprove spontaneous generation. An Italian doctor who proved maggots came from flies. (Italian 1668) Lazzaro Spallanzani - One of the first to disprove spontaneous generation. An Italian scientist who proved microorganisms could be killed by boiling. (Italian 1767) Louis Pasteur - One of the first to disprove spontaneous generation. A French scientist who proved that micro organisms was carried by dust not air. (French 1864) In 1953 Miller and Urey experiment called as electric spark experiment shows how process of formation of organic compounds or first living cell formation occur.


Is spontaneous generation valid?

Yes, it's possible with certain species. Bacteria is a living matter, and it can come from a nonliving substance. Therefore, spontaneous generation of life does occur, though it cannot occur with any species other than bacteria.


What was the purpose of the s-shape neck in pasteur's experiment?

The purpose of the s-shape neck in Pasteur's experiment was to prevent microorganisms from contaminating the sterile broth in the flask while still allowing air to circulate. The curve in the neck acted as a barrier, trapping any airborne particles that could carry microorganisms, thereby demonstrating that spontaneous generation of life did not occur in the broth.

What was the results and conclusions of the Spallanzani experiment?

Spallanzani's experiment concluded that spontaneous generation of life did not occur. By sealing containers of meat broth and boiling them to kill any existing microorganisms, he prevented the growth of microorganisms within. This demonstrated that living organisms could only arise from other living organisms.


What was the responding variable in Pasteur's experiment?

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.


How did Pasteur's experiment help show that spontaneous generation did not occur?

He demonstrated that new bacteria appeared in broth only when they were produced by living bacteria. The experiments of Redi and Pasteur helped to convince people that living things do not arise from nonliving material.


What is the hypothesis of spontaneous generation?

bacteria/ maggots etc are produced by the item which is rotting, rather than causing the rot to occur


Doing living things undergo spontaneous generation?

No, spontaneous generation has never occurred, and according to the law of biogenesis, it will never occur. The law of biogenesis, along with being the fundamental law of scientific study, states that living things can only come from living things, and this has consistenly remained correct through multifarious experiments, particularly those of Louis Pasteur and Francesco Redi. Because matter has no possibility of creating living matter, spontaneous generation has never occurred.
