What is the theory behind simple staining in microbiology?
Understand the Problem
The text is providing an overview of simple staining or monochrome staining techniques used in microbiology, explaining the principles behind staining bacteria and the types of dyes used.
Answer
Simple staining uses a single, positively charged dye to enhance contrast for viewing bacterial cells.
Simple staining uses a single, positively charged dye to bind negatively charged bacterial cells, enhancing contrast for microscopic observation.
Answer for screen readers
Simple staining uses a single, positively charged dye to bind negatively charged bacterial cells, enhancing contrast for microscopic observation.
More Information
Simple staining highlights the bacterial cell morphology by using a basic dye, which is attracted to the cell’s negative charge.
Tips
A common mistake is not leaving the dye on long enough, leading to insufficient staining.
