Vedclass · Answer

(B) Lazzaro Spallanzani demonstrated that if a nutrient broth is boiled and the flask is hermetically sealed,no microorganisms grow within it. When he broke the seal of the flask,microbial growth was observed. He concluded that microorganisms are present in the surrounding air and enter the flask when exposed. Thus,the experiment proved that when outside air enters the flask,it introduces microorganisms,thereby refuting the theory of spontaneous generation (abiogenesis).
