Question

question 1 - 8
before cell theory, people believed that living organisms arose from non - living 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. Experiments showing microorganisms couldn't grow in boiled broth when new organisms were excluded (air - free or filtered conditions) demonstrated life came from pre - existing life, supporting cell theory.

Answer:

Evidence that microorganisms cannot grow in boiled broth if all the air is removed from a container and evidence that microorganisms cannot grow in boiled broth when new organisms were not allowed to enter.
