How were Redi’s and Pasteur’s experiments different?

Redi’s experiment tested whether maggots arose spontaneously from meat. He showed that flies had to reach the meat for maggots to appear, so his experiment focused on larger organisms. Pasteur used broth and a swan-neck flask to test whether microorganisms arose spontaneously; the broth stayed free of microbes unless exposed to them. Therefore, Pasteur tested for microorganisms, while Redi studied larger organisms.
