AY Honors/Microscopic Life/Answer Key

1. List four major types of microscopics. What are some of the characteristics of each? Be able to identify the different types of microscopes from pictures, or visit a laboratory in a university or industry which has these microscopes.

2. Be able to identify the following parts of a microscope and explain or demonstrate the function of each: eye-piece or ocular, objective, body tube, nosepiece, stage, diaphragm, base, focus knob, and arm.

1. eye-piece or ocular
2. objective turret, or nosepiece
3. objective lenses
4. coarse adjustment knob
5. fine adjustment knob
6. object holder or stage
7. mirror
8. diaphragm and condenser

The eyepiece: The part of a microscope that a user looks into. (1)
Objective: (3)
Body Tube
Nosepiece: (2)
Stage: (6)
Diaphram: (8)
Base
Focus knob: (4 and 5)
Arm

To do:
edit the picture and renumber so the parts we need are in the order presented here

3. Know how to calculate the magnification of a compound microscope. Calculate the magnification of the microscope you use for this honor.

4. Define the following microscopic terms: slide, coverslip, wetmount, fixing, staining, oil immersion, unicellular, multicellular, cilia, flagella, plankton.

coverslip
wetmount
fixing
staining
oil immersion
unicellular
multicellular
cilia
flagella

5. Collect samples of water (from ponds, streams, ditches, gutters, puddles, etc.) And search for living organisms using a microscope with at least 100X magnification. Draw five of these organisms as accurately as possible. As far as possible, identify and label your diagrams (include the magnification used.)

6. Draw and label a cell which includes the following parts: cell membrane, nucleus, and cytoplasm.

7. Know the kingdoms that have microscopic life forms and know two members from each.

8. Give at least one example of how microscopic life is important for: human food, human health, medicine, other organisms.

9. Give at least three health habits that have been established as a direct result of harmful microscopic life. Put these habits into practice.
