In the context of organic chemistry, how did the designs of Pasteur's and Redi's experiments differ in demonstrating the principles of spontaneous generation?
A
Pasteur used a microscope to observe microorganisms, while Redi used chemical tests to identify organic compounds.
B
Pasteur demonstrated that life can arise spontaneously from non-living matter, while Redi showed that life cannot arise spontaneously.
C
Pasteur used a swan-neck flask to prevent microbial contamination, while Redi used sealed jars to show that maggots come from flies.
D
Pasteur used sealed jars to show that maggots come from flies, while Redi used a swan-neck flask to prevent microbial contamination.
Verified step by step guidance1
Understand the concept of spontaneous generation, which is the idea that life can arise from non-living matter.
Examine Pasteur's experiment: He used a swan-neck flask to prevent microbial contamination, demonstrating that microorganisms do not spontaneously generate but come from other microorganisms.
Analyze Redi's experiment: He used sealed jars to show that maggots on meat come from flies, not spontaneously from the meat itself.
Compare the experimental designs: Pasteur's swan-neck flask allowed air but prevented microorganisms from entering, while Redi's sealed jars prevented flies from accessing the meat.
Conclude that both experiments refuted spontaneous generation, but through different methods and observations.
