1) Assume the diameter of the field of vision in your microscope is 2mm under low power. If one Bacillus cell is 2um, how many Bacillus cells could fit end across the field? How many 10um yeast cells could fit across the field?
2) Name two ways in which you can enhance the resolving power.
3) what are the advantages of the low-power objective over the oil immersion objective for viewing fungi or algae?
4) what would occur if water were accidentally used in place of immersion oil?
5) which controls on the microscope affect the amount of light reaching the ocular lens?
6) which objective focuses closest to the slide when it is in focus?
7) why is it desirable that microscope objectives be parfocal?
8) In Bacteria, Fungi, Protozoa and algae, which one is the largest organism, which one is the smallest?
9) how does increased magnification affect the field of vision.
