Biogenesis

Vedclass · Answer

(A) Louis Pasteur's swan-neck flask experiment is a landmark study in biology that effectively disproved the theory of spontaneous generation (abiogenesis). In his experiment,he boiled nutrient broth in swan-neck flasks to kill any existing microorganisms. The curved neck allowed air to enter but trapped dust particles and microbes from the air in the bend. As long as the neck remained intact,the broth stayed sterile,proving that life does not arise spontaneously from non-living matter. When the neck was broken or tilted to allow dust to enter,microbial growth occurred. Thus,this experiment provided conclusive evidence for biogenesis,which states that living organisms arise only from pre-existing living organisms.
