What is the influence of the pH on the gram reaction in gram staining?
In what regard? You need heat in order to heat fix the bacterial cells to the slide. This adheres cells to the slide. Otherwise, the bacterial cells would wash off the slide during the Gram staining process. If you leave the slide in the Bunsen burner too long, then you can distort the bacterial cell shape and size and also have other artifacts appear on the slide that are not bacterial cells.

Why do cheek lining cells appear purple?
The nucleus at the central part of the cheek cell contains DNA. When a drop of methylene blue is introduced, the nucleus is stained, which makes it stand out and be clearly seen under the microscope. Although the entire cell appears light blue in color, the nucleus at the central part of the cell is much darker, which allows it to be identified.

Why do yeast cells appear larger than bacterial cells when observed under a microscope?
Yeast are cultured for longer periods of time than bacteria because they are 5 to 10 times bigger than bacteria.
Why is methylene blue is an appropriate dye for staining bacterial cells?
It is used in gram staining to differentiate gram negative and gram positive bacteria. After being dyed, the cells are washed with ethanol. Gram positive bacteria will retain the methylene blue due to the amount of peptidoglycan in their cell walls, where gram negative cells will not. Iodine is used as a counter stain, which is up-taken by gram negative cells. After the gram staining procedure is finished, gram positive cells will appear dark purple or blue due to the retained methylene blue. Gram negative cells will appear pink or red due to the iodine counter stain.
What would be the result of overheating the bacterial smear?
