When using the light microscope: A- You always start with a high power and work your way down in magnification because the microscopes we have are parfocal. B- You always use immersion oil with the 40X objective to get the best image. C- Organisms are usually stained when using brightfield microscopy. D- The advantage of darkfield is being able to view live, unstained (and sometimes motile) cells.

In what situation, or situations, would the use of a light microscope be ideal? Why? a. A light microscope is used to view the details of the surface of a cell as it cannot be viewed in detail by the transmission microscope. b. A light microscope allows visualization of small living cells, which have been stained and cannot be viewed by scanning electron microscope. c. A standard light microscope is used to view living organisms with little contrast to distinguish them from the background, which would be harder to see with the electron microscope. d. A light microscope reveals the internal structures of a cell, which cannot be viewed by transmission electron microscopy.
When using a microscope, low power should always be used initially for all of the following reasons except: A. as part of the beginning process of viewing a specimen. B. to focus in on the desired area of the section. C. to scroll through a large area of the slide. D. to avoid damaging the objective lenses. E. to view the specimen with as much detail as possible. I should always make sure the light wheel is turned all the way down to the lowest position and then turn off the microscope - in that order. True False
