Question

Which one of the following experiment suggests that simplest living organisms could not have originated spontaneously from non-living matter?

• A. Larvae could appear in decaying organic matter
• B. Microbes did not appear in stored meat
• C. Microbes appeared from unsterilized organic matter
• D. Meat was not spoiled, when heated and kept sealed in a vessel

Answer 1

The correct option is D Meat was not spoiled, when heated and kept sealed in a vessel

• The heating of meat killed the pre-existing micro-organisms and then the meat was kept in a sealed vessel, so that no organism can come from outside.
• In these conditions, no new microorganisms could be produced and meat would not be spoiled, because new micro-organisms cannot be produced by dead micro-organisms present in meat, and also no new micro-organisms are allowed from outside.

So, the correct answer is option D.
