Question

question 1 - 8
before cell theory, people believed that living organisms arose from nonliving matter. what evidence resulted in cell theory eventually replacing the concept of spontaneous generation?

• evidence that microorganisms can be filtered out with contaminated particles
• evidence that microorganisms cannot grow in boiled broth if all the air is removed from a container
• evidence that microorganisms cannot grow in boiled broth when new organisms were not allowed to enter

Explanation:

Cell theory replaced spontaneous generation when experiments showed that microorganisms could not grow in boiled broth when new organisms were not allowed to enter. This demonstrated that life comes from pre - existing life, not from non - living matter.

Answer:

evidence that microorganisms cannot grow in boiled broth when new organisms were not allowed to enter
