Question

Describe Pasteur’s results and how they helped disprove spontaneous generation. HURRY PLZ!!

Answer 1

Answer: Pasteur used a special flask to demonstrate that heating a liquid kills bacteria. His experiments also showed that the broth would stay clear if the bacteria were trapped in the flask’s neck. If he broke the neck off the flask, the broth was soon full of bacteria. Only broth that had bacteria to begin with would grow more bacteria. Life does not spontaneously generate; all life must come from existing life.

Answer 2

Pasteur-Disproved spontaneous generation using S-necked flasks that were open to the air but did not let microorganisms in. Broth boiled in the flasks did not become contaminated. The organisms could have come from the air and settled into the broth. To disprove the theory of spontaneous generation, Louis Pasteur devised a way to the flask that allowed oxygen in but prevented dust from entering. Through this experiment, Pasteur demonstrated that life arises from existing life.
