The purpose was so the flies won't get in the jar.
Francesco Redi disproved the theory of spontaneous generation in larger organisms during the 1600s with this experiment. By using flasks containing meat -- one open and one sealed -- Redi discovered that maggots only appeared on the uncovered meat that could be accessed by flies. The maggots were hatching from eggs laid on the meat, not from the meat itself. Pasteur continued the experimentation regarding spontaneous generation in the 1800s with the growth of bacteria on soup.

meat and flies
Redi did an experiment seeing what maggots come from by putting meat into jars and left 1 open 1 covered with netting and one sealed the only one that didn't get maggots was the one that was sealed proving that maggots come from flies.
redi?
He was a scientist who experimented with maggots and meat and found out that maggots did not grow on meat
In the 1600's, the Italian scientist Francisco Redi performed experiments that showed that flies did not spontaneously generate from raw meat.

The purpose was so the flies won't get in the jar.
Flies are attracted to meat and will lay eggs on the meat, where they quickly hatch into maggots. But the flies are not indigenous to the meat.
Redi used a jar, meat and gauze. The gauze kept the flies off the meat. Redi's hypothesis was that if you kept flies away from the meat, maggots would not appear, because the flies did not lay eggs on the meat.
no it doesnt
Rotting meat doesn't create flies. Rotting meat attracts flies that lay their eggs on the meat. These eggs hatch and maggots emerge and proceed to feed off the rotten meat. After a period as a chrysalis, the maggots change and emerge as adult flies.
because they always appear where meat is rotting
Flies will often lay eggs on spoiled meat because they are attracted to the smell of the meat. The meat will provide a place for the eggs to incubate and also a source of food once the larvae hatch.
