What is the primary purpose of staining cells on a microscope slide?

• A. Reduce the magnification required to view cellular structures
• B. Prevent the cells from drying out under the microscope
• C. Increase the contrast between cells and their background for better visualization
• D. Enhance the rate of cell division during observation

Answer: (C)

Verified step by step guidance

1. Understand that cells are mostly transparent and colorless under a microscope, making it difficult to see their structures clearly.
2. Recognize that staining introduces color to the cells or their components, which helps differentiate them from the background and from each other.
3. Know that the primary purpose of staining is to increase the contrast between the cells and the surrounding medium, improving visibility and detail.
4. Note that staining does not reduce magnification or prevent drying, nor does it affect the biological processes like cell division during observation.
5. Conclude that the correct purpose of staining is to enhance visualization by increasing contrast, allowing for better examination of cellular structures.
