Which type of microscope is commonly used to visualize most types of bacteria?

• A. Atomic force microscope
• B. Light microscope
• C. Confocal laser scanning microscope
• D. Electron microscope

Answer: (B)

Verified step by step guidance

1. Understand the different types of microscopes listed: Atomic force microscope, Light microscope, Confocal laser scanning microscope, and Electron microscope.
2. Recall that bacteria are typically in the size range of about 0.2 to 10 micrometers, which influences the choice of microscope for visualization.
3. Recognize that the light microscope uses visible light and lenses to magnify specimens, making it suitable for viewing most bacteria at magnifications up to around 1000x to 2000x.
4. Note that electron microscopes provide much higher resolution but are more complex and typically used for detailed ultrastructural studies rather than routine bacterial observation.
5. Conclude that the light microscope is the most commonly used microscope to visualize most types of bacteria because it balances ease of use, cost, and sufficient magnification for general bacterial observation.
