Question

the names of the microscope parts in column a with the descriptions in column b. place the letter of your choice in the space provided.
column a
a. adjustment knob (coarse)
b. arm
c. condenser
d. eyepiece (ocular)
e. field of view
f. iris diaphragm
g. nosepiece
h. objective lens system
i. stage
j. stage (slide) clip

column b
______ 1. increases or decreases the light intensity
______ 2. platform that supports a microscope slide
______ 3. concentrates light onto the specimen
______ 4. causes stage (or objective lens) to move upward or downward
______ 5. after light passes through the specimen, it next enters this lens system
______ 6. holds a microscope slide in position
______ 7. contains a lens at the top of the body tube
______ 8. serves as a handle for carrying the microscope
______ 9. part to which the objective lenses are attached
______ 10. circular area seen through the eyepiece

Explanation:

To solve this, we match each microscope part in Column A with its correct description in Column B by recalling the function of each part:

1. Iris diaphragm (f) controls light intensity, so 1 - f.
2. Stage (i) is the platform for the slide, so 2 - i.
3. Condenser (c) concentrates light, so 3 - c.
4. Coarse adjustment knob (a) moves stage/lens, so 4 - a.
5. Objective lens system (h) is next after specimen, so 5 - h.
6. Stage clip (j) holds slide, so 6 - j.
7. Eyepiece (d) has lens at top, so 7 - d.
8. Arm (b) is the handle, so 8 - b.
9. Nosepiece (g) holds objectives, so 9 - g.
10. Field of view (e) is the circular area, so 10 - e.

Answer:

1. f. Iris diaphragm
2. i. Stage
3. c. Condenser
4. a. Adjustment knob (coarse)
5. h. Objective lens system
6. j. Stage (slide) clip
7. d. Eyepiece (ocular)
8. b. Arm
9. g. Nosepiece
10. e. Field of view
