Detailed explanation-1: -Redi went on to demonstrate that dead maggots or flies would not generate new flies when placed on rotting meat in a sealed jar, whereas live maggots or flies would. This disproved both the existence of some essential component in once-living organisms, and the necessity of fresh air to generate life.

Detailed explanation-2: -Disproving Spontaneous Generation In 1858, Pasteur filtered air through a gun-cotton filter and, upon microscopic examination of the cotton, found it full of microorganisms, suggesting that the exposure of a broth to air was not introducing a “life force” to the broth but rather airborne microorganisms.

Detailed explanation-3: -Redi concluded that the flies laid eggs on the meat in the open jar which caused the maggots. Because the flies could not lay eggs on the meat in the covered jar, no maggots were produced. Redi therefore proved that decaying meat did not produce maggots.

Detailed explanation-4: -Redi’s experiment proved that life, maggots, from non life, meat, was superstition. propagandizing the ancient Greek spontaneous generation superstitions of 2, 300 years earlier. Figure 2. Pasteur’s experiments proved that microorganisms come from life, not non life.
