Honors Cells, Microscopes and Transport Review

1. Turning which of the following knobs moves the objective lenses the greatest vertical distance?

• Course adjustment knob
• Fine adjustment knob
• Microscope knob
• How many more days until Turkey day?

2. The major difference between a Simple Microscope and Compound Microscope is that..... (There are 2 correct answers (select both))

• Simple Microscopes are more expensive than Compound Microscopes
• Simple Microscopes use two lenses while Compound Microscopes use three
• Simple Microscopes are smaller than Compound Microscopes
• Simple Microscopes use one lens while Compound Microscopes use two or more

3.The first lens is 40X. The second lens is 10x. The total magnification of the object in view is

• 40X
• 50X
• 400X
• 4000X

4. The part of the microscope that contains the magnifying lens through which we look is called

• objective eye lens
• Eye piece
• ocular diaphragm
• Stage

5.When referring to the sharpness of an image while using a microscope it is commonly called

• Magnification
• Clarity
• Resolution
• Pixels

6. What is the correct formula to calculate total magnification?

• Objective lens magnification divided by the ocular lens magnification
• Objective lens magnification added to the ocular lends magnification
• Objective lens magnification multiplied by the ocular lens magnification
• Ocular lens magnification subtracted by objective lens magnification

7.The image on the left is a picture of pollen. The specimen was viewed with a __________

• Compound Light microscope
• Scanning Electron microscope
• Super Duper Mega electron microscope
• Dissecting microscope

8. Compound Light microscopes (like the ones we have in our class)

• work by reflecting electrons off the surface of an object being studied.
• can generally magnify objects about 10,000 times without being blurry.
• use light and glass lenses to magnify an image.
• typically provide more resolution than an electron microscope.

9. Which part of the microscope holds the three objective lenses, and rotates around in a circle, allowing you to choose which objective lens you want to use?

• Revolving nose piece
• Rotating Diaphragm
• Revolving objective lens thingy
• Rotating body tube

10. Select the correct answer below that explains the differences between a SEM and a TEM

• SEM scans the surface of an object while a TEM shows the interior structure.
• SEM shows the inside of an object while a TEM scans the surface
• There is no difference. Scientists just created different names to confuse students.
