Question

match 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:

1. The adjustment knob (coarse) increases or decreases light intensity.
2. The platform that supports a microscope - slide is the stage.
3. The condenser concentrates light onto the specimen.
4. Causing the stage (or objective lens) to move upward or downward is done with the adjustment mechanism related to focusing.
5. After light passes through the specimen, it enters the objective lens system.
6. Holding a microscope slide in position is the function of the stage (slide) clip.
7. The nosepiece contains a lens at the top of the body - tube.
8. The arm serves as a handle for carrying the microscope.
9. The part to which the objective lenses are attached is the nosepiece.
10. The circular area seen through the eyepiece is the field of view.

Answer:

1. a. Adjustment knob (coarse)
2. h. Stage
3. c. Condenser
4. (Not clearly matched in given options, but related to focusing mechanism)
5. h. Objective lens system
6. i. Stage (slide) clip
7. g. Nosepiece
8. c. Arm
9. g. Nosepiece
10. d. Field of view
