- What is the purpose of fixing a smear? Mark all that apply: 1. To attach the bacteria to the slide 2. To cause the cells to shrink and become distorted 3. To kill the bacteria so they aren't harmed by the staining method 4. To break down the cell wall in order to make the cells accept stain 5. To kill the bacteria to make the slide safer to handleIn your own words, explain how gram staining is done and how it works.This part of the staining process helps the primary stain to remain in the cell during decolorization. O 1) Secondary stain O 2) primary stain O 3) counterstain O 4) fixing reagent O 5) mordant
