- Which one of these techniques does not distinguish between live and dead cells? Group of answer choices Coulter count fluorescence staining spread plateBased from the results obtained from Gram staining, explain why bacterial cells retained or changed their color. Briefly explain the principle behind the procedure. Cite advantages of differential staining method (Gram staining and endospore staining) over simple staining only. List other staining methods aside from those you performed in the laboratory. conclusion:Gram-positive (+) bacteria with a thin peptidoglycan layer traps the crystal violet stain. Select one: True False

- Select all that apply to a direct simple stain: 1. the dye is acidic or negatively charged and stains the background 2. uses multiple dyes in the procedure 3. cells will never be distorted or shrunken 4. uses only 1 dye in the procedure 5. does involve a washing step 6. can be used to determine cell morphology, size, and arrangement. 7. does involve fixing 8. the dye is basic or positively charged and stains the bacteria 9. cells may be distorted or shrunken 10. does not involve a washing step 11. does not involve fixingWhat 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 handleDescribe the Gram staining procedure
