1. Microscope Parts & Usage

2. Contains the magnifying lens you look through.
EYEPIECE

3. Which objective lens would you use for first focusing the object?
SCANNING

4. Scientist known for contributing to the third part of the ‘Cell Theory’ which states that all cells come from other cells.
VIRCHOW

5. Maintains the proper distance between the eyepiece and the objective lenses.
BODY TUBE
(BARREL)

6. Which adjustment knob should be used on scanning power?
COARSE ADJUSTMENT KNOB

7. Scientist who observed “animalcules”, also known as bacteria and protozoan.
Van LEEUWENHOEK

8. Supports the body tube and stage; used to carry the microscope.
ARM

9. Statements about cells that apply to all living things developed with use of the microscope.
CELL THEORY

10. Which adjustment knob should be used while on high power?
FINE ADJUSTMENT KNOB

11. Scientist who observed the first cells and came up with the word ‘cells’.
HOOKE

12. Located on the stage, holds the slide in place.
STAGE CLIPS
(SLIDE CLIPS)

13. The name for a microscope with one ocular lens (eyepiece).
MONOCULAR

14. Scientist who studied plant cells and helped contribute to the ‘Cell Theory’.
SCHLEIDEN

15. COARSE ADJUSTMENT KNOB
Moves the stage up and down for focusing an image; used first when focusing the specimen.
COARSE ADJUSTMENT KNOB

16. Term used to describe a microscope with two sets of magnifying lenses.
COMPOUND

17. Moves the stage slightly to sharpen the focus of the image; used only with the higher power objective lenses.
FINE ADJUSTMENT KNOB

18. Scientist who studied animal cells and helped contribute to the ‘Cell Theory’.
SCHWANN

19. Provides electricity in order to operate the microscope.
POWER SWITCH

20. A tool used to view small objects that cannot be easily seen by the naked eye.
MICROSCOPE

21. Holds the objective lenses and allows them to be rotated during use.
NOSEPIECE

22. This term is used to describe a microscope that remains focused on high power once focused on scanning power.
PARFOCAL

23. Magnifying lenses located closest to the specimen being viewed.
OBJECTIVE LENSES

24. The white circle you see when you look through the eyepiece with the light turned on.
FIELD OF VIEW
(VIEWING CIRCLE)

25. Allows light to go through the stage, specimen, and the lenses to your eye.
STAGE OPENING
(APERTURE)

26. What is the formula used to calculate total magnification?
OCULAR LENS x THE OBJECTIVE LENS IN USE
(ex. 10x times 40x = 400x)

27. Supports the slide being viewed; should be all the way up before first focusing the specimen.
STAGE

28. Scientist given credit for developing the first microscope.
JANSSEN

29. Regulates the amount of light allowed through the specimen and into the body tube.
DIAPHRAGM

30. (NOT THROUGH THE EYEPIECE)
Where should you look when changing from the scanning power to a higher power?
TO THE SIDE OF THE STAGE
(NOT THROUGH THE EYEPIECE)

31. Provides light necessary to view the specimen.
LAMP
(LIGHT SOURCE)

32. Supports the weight of the entire microscope; used to carry the microscope.
BASE

33. Which objective lens provides the greatest field of view?
SCANNING
