GCSE Biology - What Is The Difference Between Light And Electron Microscopes? #6

The video tutorial explains the differences between light and electron microscopes. Light microscopes are small, easy to use, and affordable, making them suitable for classroom use. However, their resolution is limited to 0.2 micrometres due to the wavelength of light. Electron microscopes, while large and expensive, offer a much higher resolution of 0.1 nanometers, allowing for detailed study of subcellular structures like mitochondria. The video highlights the pros and cons of each type, emphasizing the superior resolution of electron microscopes, which is 2000 times better than that of light microscopes.

What is a key advantage of light microscopes that makes them popular in educational settings?

• They can view sub-cellular structures like mitochondria.

• They are used exclusively in laboratories.

• They are small, easy to use, and affordable.

• They have a high resolution of 0.1 nanometers.

Why are electron microscopes primarily used in laboratories?

• They are inexpensive and portable.

• They are small and easy to use.

• They are large, expensive, and complex to operate.

• They have a resolution limited to 0.2 micrometres.

What is the resolution capability of electron microscopes?

• 0.2 micrometres

• 0.2 nanometers

• 0.1 micrometres

• 0.1 nanometers

How much better is the resolution of electron microscopes compared to light microscopes?

• 500 times better

• 100 times better

• 1000 times better

• 2000 times better

What can electron microscopes reveal that light microscopes cannot?

• The overall shape of cells

• The color of cells

• The movement of cells

• Sub-cellular structures like mitochondria
