Understanding the Compound Microscope

This video tutorial introduces the compound microscope, a crucial tool in biology for magnifying small objects. It explains the principles of magnification and resolution, and identifies the various parts of a compound microscope, including magnifying, mechanical, and illuminating components. The tutorial highlights the functions of each part and their role in studying microorganisms and other small specimens.

What is the primary function of a microscope in biology?

• To measure temperature

• To magnify small objects

• To record sound

• To create artistic images

What does 40x magnification mean?

• The object is 400 times larger

• The object is 4 times larger

• The object is 40 times larger

• The object is 40 times smaller

Which part of the microscope is used to view the specimen?

• Base

• Ocular

• Stage

• Objective

What is the typical magnification range of the ocular lens?

• 15x to 25x

• 5x to 15x

• 1x to 5x

Which part of the microscope connects the eyepiece to the objectives?

• Stage

• Body tube

• Base

• Draw tube

What is the function of the coarse adjustment knob?

• To focus the image under low power

• To adjust light intensity

• To change objectives

• To hold the slide in place

What is the role of the mirror in a microscope?

• To magnify the specimen

• To adjust the focus

• To gather and direct light

• To hold the specimen

How does the diaphragm affect the light in a microscope?

• It focuses the light

• It regulates the amount of light

• It blocks the light

• It changes the color of the light

What is one major benefit of using a microscope in biological studies?
