Staining cells such that their color differs based on the type of cell wall structure is the basis of which staining technique?

• A. Gram staining
• B. Endospore staining
• C. Negative staining
• D. Simple staining

Answer: (A)

Verified step by step guidance

1. Understand that the question is asking about a staining technique that differentiates cells based on their cell wall structure.
2. Recall that Gram staining is a differential staining technique that classifies bacteria into Gram-positive and Gram-negative based on differences in their cell wall composition.
3. Recognize that endospore staining is used to detect endospores, not to differentiate cell wall types.
4. Know that negative staining stains the background and is used to visualize capsules, not cell wall differences.
5. Simple staining uses one dye and does not differentiate between cell types based on cell wall structure.
