Simple staining is a procedure often used to increase the contrast of _____________ microscopes.

• A. Dark-field microscopes.
• B. Fluorescence microscopes.
• C. Compound light (brightfield) microscopes.
• D. Transmission electron microscopes.

Answer: (C)

Verified step by step guidance

1. Understand the purpose of simple staining: Simple staining is used to increase the contrast of specimens under a microscope, making it easier to observe the morphology and arrangement of cells.
2. Identify the types of microscopes: The problem mentions several types of microscopes, including dark-field, fluorescence, compound light (brightfield), and transmission electron microscopes.
3. Consider the characteristics of each microscope: Compound light (brightfield) microscopes use visible light to illuminate specimens, which can be enhanced by simple staining to improve contrast.
4. Evaluate the role of simple staining in microscopy: Simple staining is particularly useful in brightfield microscopy because it enhances the visibility of transparent or lightly colored specimens by adding color contrast.
5. Conclude the application: Recognize that simple staining is most commonly associated with compound light (brightfield) microscopes, as it directly addresses the need for increased contrast in this type of microscopy.
