It helps the cells adhere to the slide so that they can be stained.
The purpose of heat fixing is to kill the organisms without serious distortion. They adhere better to the slide and also take up dye more easily.

Purpose of fixing the bacterial film?
The purpose of heat fixing the bacteria to the slide is so during the gram staining procedure the bacteria doesn't wash off. If you didn't heat fix the bacteria to the slide, it would not stay on the slide.
What are the advantage and disadvantage of heat fixing?
adv..... heat fixing inactivates enzymes that would normally disrupt cell morphology and structure during staining and observation. dis....... if not done well much of the specimen can be destroyed in heat fixing.
Why is the slide not heat fixed before negative staining?
First and foremost, the purpose of heat fixing is to drive stain into the bacterial cells, which in this case, you are staining the background, so there is not a need for heat fixing. Next, the process of heat fixing will shrink the cell by a little. This sorts of support the first reason as since there isn't the need to heat fix, then don't. By not heat-fixing, we actually see a more accurate morphology, arrangement and size of thr bacterial cell. Hope that my answers helps 😊
What would happen if no fixing were done?
If no heat fixing was done to a slide with a specimen on it, it would be rinsed off with the gram staining procedure. Heat fixing the specimen does kill specimen but it also locks it in place.
What is fixing?
a heat fix is something you put on the slide
What will happen if too much heat is applied while heat fixing a slide?
When too much heat is applied during the heat fixing of a slide with a bacterial cell on it, the cell would explode. The membrane of the cell would rupture.
What would happen if no heat fixing were done?
If no heat fixing was done to a slide with a specimen on it, it would be rinsed off with the gram staining procedure. Heat fixing the specimen does kill specimen but it also locks it in place.
What is Passing a slide sample through a flame is called?
heat fixing
When was Jammy Smears created?
Jammy Smears was created in 1976.
Does Heat fixing sterilize slide?
I guess so, and that's why you put out the flame after that.
What effect does heat fixing have on bacterial cell size?
it makes cell size shrink
What is the loss of carbon-fixing activity of the enzyme RuBP carboxylase directly proportional to?
heat
