He demonstrated that new bacteria appeared in broth only when they were produced by living bacteria. The experiments of Redi and Pasteur helped to convince people that living things do not arise from nonliving material.

What is the broth in the flask?
In a science experiment, a broth is a liquid and a flask is a particular shape of glassware. If the method of your experiment refers to "the broth in the flask", look back over the previous steps and figure out what chemicals and liquids you added to the flask. If the goal of the experiment is to determine what the unknown broth in the flask is you may have to determine it by observing it's physical and chemical traits, be careful with the unknown broth in case it is flammable, poisonous or otherwise dangerous.

How did Pasteurs experiment answer the objections raised by supporters of the vital force hypothesis?
Pasteur's experiment permitted air from the outside to mix with air from the inside, which would have allowed any "vital force" to enter and cause the broth to become cloudy if there were such a "vital force.

Agar, because broth is a natural fuel source for bacteria, whilst some types of agar are scientifically created, which makes it supreme for growing bacteria.
