Unit 2 light microscopes (compound & dissecting)

When observing cells, which of the following pieces of equipment is most appropriate?

• Hand lens
• Telescope
• Petri dish
• Microscope

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

Two types of microscopes are shown in the diagram above. Which statement describes the main difference between the dissecting microscope and the compound microscope?

• The dissecting microscope has one fewer lens than the compound microscope.

• The dissecting microscope uses an electric bulb for light, and the compound microscope uses sunlight.

• The dissecting microscope has a small viewing stage and the compound microscope has a large viewing stage.

• The dissecting microscope is used to view larger objects, and the compound microscope is used to view very small objects.
