This process enhances the contrast in the microscopic image, allowing scientists to observe structures within the cells more clearly. It is a fundamental technique in microbiology and assists in identifying and studying the morphology and biochemical properties of microorganisms.

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 handle
Why is it important to limit the quantity of cells used to prepare a smear? Mark all that apply: O So that cells are not clumped and don't entrap stain creating erroneus results So that no contaminants are introduced onto the slide by being entrapped in clumps OSo that the cells are spread out enough that cell morphology can be discerned OSo that the cells are spread out enough that the arrangement can be observed O So that there are small groups of cells clumped together to make them visible Microsoft Bing 11:31 AM 87°F Sunny 9/14/2021

Before viewing a specimen of pigmented bacteria on a slide under the light microscope, which of the following usually needs to happen (and why)? Staining (to increase magnification). Heat, radiation or antimicrobial chemical treatment (to kill the bacteria for safe observation). Add immersion oil (to increase resolution). Add a cover slip (to reduce contamination). The viewing chamber needs to be flushed of air (to create a vacuum).
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
