A 19th century scientist investigates cell growth by placing boiled broth in one Erlenmeyer flask and non-boiled broth in another flask. The scientist covered both flasks so that air could not enter the flasks and observed the flasks for two weeks. Neither flask grew any biological matter. From this the scientist concluded that abiogenesis or spontaneous generation was an invalid theory.Select the best evaluation of the above experiment and conclusion
  • a)
    The conclusion is an invalid conclusion because living objects often require air to grow regardless if their origin was spontaneous or not.
  • b)
    Since no colonies of cells grew in either flask, the conclusion is a valid conclusion because cells can only grow from other cells.
  • c)
    Since no colonies of cells grew in either flask, the conclusion is a valid conclusion because spontaneous generation predicts that cells should grow spontaneously.
  • d)
    The conclusion is an invalid conclusion because the scientist did not wait long enough for anaerobic cells to grow in the broth.
Correct answer is option 'A'. Can you explain this answer?

The experiment described involves the use of boiled broth and non-boiled broth, both of which are covered to prevent the entry of air. The observation that no growth occurred in either flask cannot be solely attributed to the rejection of spontaneous generation. The absence of growth could be due to the lack of essential nutrients or gases necessary for cell growth, such as oxygen. Therefore, the conclusion that spontaneous generation is an invalid theory based solely on this experiment is not justified, as it does not account for the potential influence of other factors necessary for cell growth.
