Question
Which of the following is true about simple staining?
Correct Answer
Option C is the correct answer.
Detailed Explanation
Simple staining involves using a single basic dye to stain all cells in a smear, producing a uniform color contrast against the unstained background. India ink and Nigrosin are used in negative staining, which stains the background, not the cells. Differential staining (like Gram stain) requires two or more dyes.
Hint
Consider the primary goal of simple staining in microscopy, which is to make cells visible under the microscope by coloring them uniformly.
