Question

Spallanzi did experiments to disprove the law of spontaneous generation. He sealed his jars so that air could not get in. Supporters of spontaneous generation argued that without air nothing could live. How did Pasteur’s experiment show once and for all that spontaneous generation does not occur?

Answer 1

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