Help with AP Biology Lab 3?

I need help with the experiment where you prepare a garlic root tip squash. I am trying to write a hypothesis, but I don't understand why you put the specimen over the flame before you look for the stages of mitosis. Already looked at LabBench and couldn't find anything on it. Any help. Thanks.
