Microscopes and Cell Theory

This image shows the detailed structure of the tiny mitochondria organelle.  Which microscope most likely took this image?

• Compound Light
• Scanning Electron
• Dissecting
• Transmission Electron

Light microscopes

• Are generally not used to view bacteria
• Work by reflecting electrons off the surface of an object being studied
• Typically provide more resolution than an electron microscope
• Use light and glass lenses to magnify an image

Which of the following is a disadvantage of both the TEM and SEM?

• Low magnification
• Cannot observe living specimens
• High resolution

Which type of microscope is the MOST suitable for observing the surface of a virus?

• Transmission Electron Microscope
• Confocal Microscope
• Bright Field Microscope
• Scanning Electron Microscope

Electron microscopes use a beam of _________________ to produce an image magnified up to 100,000 or more

• Sunlight
• Lasers
• Electrons
