Homework Answers
Answer 11. Each cell will be approx. 0.5mm long. Because there are 4 cells present end-to-end as 1-2-3-4. Diameter is 2mm means 2/4 = 0.5mm.
Answer 12. High power objective lens means 40X. If the eyepiece is 10X then total magnification is 10 X 40 = 400 times as that of the naked eye.

1. Fill out the following table by indicating which general technique (light microscopy (LM) or electron microscopy (EM]) could be used to observe each structure or phenomenon. Put "no" in the box if the technique could not be used. If light microscopy can be used, name one technique (bright-field, phase-contrast, fluorescence, etc.) that you think would be effective. You will find some useful information in Appendix 1 of this manual and Chapter 18 of your textbook. Structure or phenomenon Could...
