Question
Which of the following is true about simple staining?
Correct Answer
Option C is the correct answer.
Detailed Explanation
Simple staining uses a single basic dye (e.g., methylene blue, crystal violet) to color all bacterial cells uniformly. This increases the contrast between the cells and the background, making their morphology and arrangement easily observable. Options A and B describe negative staining and differential staining, respectively. Option D is incorrect, as a smear is typically required.
Hint
Think about the primary goal of using a single dye to stain bacteria.
