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 Column B
a. Adjustment knob (coarse) 1.   Increases or decreases the light intensity
b. Arm 2.   Platform that supports a microscope slide
c. Condenser 3.   Concentrates light onto the specimen
d. Eyepiece (ocular) 4.   Causes stage (or objective lens) to move upward or downward
e. Field of view 5.   After light passes through the specimen, it next enters this lens system
f. Iris diaphragm 6.   Holds a microscope slide in position
g. Nosepiece 7.   Contains a lens at the top of the body tube
h. Objective lens system 8.   Serves as a handle for carrying the microscope
i. Stage 9.   Part to which the objective lenses are attached
j. Stage (slide) clip 10.   Circular area seen through the eyepiece

Adjustment knob (coarse) ---> Causes stage (or objective lens) to move upward or downward

Arm ---> Serves as a handle for carrying the microscope

Condenser ---> Concentrates light onto the specimen

Eyepiece (ocular) ---> Contains a lens at the top of the body tube

Field of view ---> Circular area seen through the eyepiece

Iris diaphragm ---> Increases or decreases the light intensity

Nosepiece ---> Part to which the objective lenses are attached

Objective lens system ---> After light passes through the specimen, it next enters this lens system

Explanation:

The microscope is an essential equipment used in science laboratories to view objects which are too small to be seen by the naked eye. Also certain processes which occur at the microscopic level can only be observed using a microscope.

There are many different types of microscopes. The compound light microscope is the one most commonly used in biological laboratories to view tissues and cells of organisms. It uses visible light which passes through two separate lens to magnify the image produced of a specimen.

The various parts of compound light microscope and their respective functions are given below:

Adjustment knob (coarse) ---> Causes stage (or objective lens) to move upward or downward

Arm ---> Serves as a handle for carrying the microscope

Condenser ---> Concentrates light onto the specimen

Eyepiece (ocular) ---> Contains a lens at the top of the body tube

Field of view ---> Circular area seen through the eyepiece

Iris diaphragm ---> Increases or decreases the light intensity

Nosepiece ---> Part to which the objective lenses are attached

Objective lens system ---> After light passes through the specimen, it next enters this lens system

Stage ---> Platform that supports a microscope slide

Stage (slide) clip ---> Holds a microscope slide in position
