Redi experiment:
Answer variants:
The decaying meat in the jar attracted flies and, flies entered and layed eggs which eventually gave birth to new larvae in the uncovered jar.
In the jar covered with cork and gauze, flies were unable to enter the jar. Hence, no larvae were found.
He left one of the jars uncovered, one sealed with a cork and the other with gauze.
Hence, through this experiment, he proved that life spontaneously originated from pre-existing life (flies) rather than non-living material (cooked meat).
He left one of the jars uncovered, one sealed with a cork and the other with gauze.
He took cooked meat so that no living organisms are alive in it and placed them in three different jars.
