Types of Microscopes

Front

What are the 4 main types of microscopes?

Back

Compound light microscopes, dissecting microscopes, scanning electron microscopes, and transmitting electron microscopes.

Front

What is the primary function of a compound light microscope?

Back

To magnify small objects using visible light and lenses.

Front

What is the primary function of a dissecting microscope?

Back

To provide a 3D view of the surface of a specimen, often used for dissection.

Front

What is the primary function of a scanning electron microscope?

Back

To scan the surface of a specimen with a focused beam of electrons to create detailed images.

Front

What is the primary function of a transmitting electron microscope?

Back

To transmit electrons through a specimen to view its internal structure in high detail.

Front

How do compound light microscopes and dissecting microscopes differ in function?

Back

Compound light microscopes are used for magnifying small objects with light, while dissecting microscopes provide a 3D view for dissection purposes.

Front

How do scanning electron microscopes and transmitting electron microscopes differ in function?

Back

Scanning electron microscopes create detailed surface images, while transmitting electron microscopes view internal structures.

Front

What type of microscope would be best for viewing living plant cells?

Back

Light microscope - Dissecting is not powerful enough and electron microscopes can only be used to view dead specimens because they require the use of a vacuum.

Front

What type of microscope would be best for taking a closer look at patterns on a butterfly wing?

Back

A dissecting microscope; specimens in a light microscope need to be thin enough for light to penetrate them. Electron microscopes are used to view extremely tiny dead specimens.
