Study Notes
Microscopes Comparison
- The primary difference between dissecting and compound microscopes is their application: dissecting microscopes are used to examine larger samples, such as organs or insects, while compound microscopes are used to study smaller samples, like cells and microorganisms.
Electron Microscope vs Compound Microscope
- Electron microscopes differ from compound microscopes in that they use a beam of electrons instead of light to produce an image, allowing for higher resolution and magnification.
Scanning Electron Microscope (SEM)
- The SEM produces a three-dimensional view of the sample surface, similar to a dissecting microscope.
- Electron microscopes, including SEM, can produce high-resolution, two-dimensional views of thinly sliced cells.
Disadvantages of Electron Microscopy
- A significant drawback of using electron microscopy compared to light microscopy is that samples must be dehydrated and coated with metal, which can be time-consuming and may alter the sample.
Compound Microscope Applications
- Compound microscopes are suitable for viewing subcellular structures and thinly sliced tissues and individual cells as small as bacteria due to their high magnification power and resolution.
Dissecting Microscope Function
- The primary function of a dissecting microscope is to examine larger samples, such as organs or insects, in three dimensions.
Microscope Selection
- For examining the surface of small organisms, like insects, a dissecting microscope is best suited.
- A compound microscope is ideal for viewing thinly sliced tissues and individual cells as small as bacteria.
- Electron microscopes, including SEM, are used to produce high-resolution, two-dimensional views of thinly sliced cells.
