7. Mr. Kwach presented his grade learners with a chart having microscopes shown below. Study them.

a) Give two functions of a microscope

• To magnify small objects, making them visible to the naked eye.
• To resolve fine details of specimens, allowing differentiation between closely spaced structures.

b) Identify the type of microscope represented by
G: Light microscope (or Compound microscope)
H: Electron microscope

c) What does microscope H use for:

i) Magnification: Electron beams and electromagnetic lenses

ii) Resolution: Electron beams

d) State any four differences between the microscopes G and H

• Microscope G uses light as its source of illumination, while microscope H uses an electron beam.
• Microscope G uses glass lenses, while microscope H uses electromagnetic lenses.
• Microscope G has lower magnification (up to approximately 1500x), while microscope H has much higher magnification (up to millions of times).
• Microscope G has lower resolution, while microscope H has much higher resolution.
• Microscope G can view live or dead specimens, while microscope H can only view dead specimens in a vacuum.
• Microscope G produces a color image viewed through an eyepiece, while microscope H produces a black and white image viewed on a screen.
