A Transmission Electron and Light Microscope

B Scanning Electron and Light Microscope

C Binocular dissecting and scanning electron microscopes

D None of the answers are correct

When entering the parts of the microscope on the picture, use the exact name of the part given to you on the following page (pg 15).

(your answer will be a number followed by "x" - no spaces between)

#6. Use a piece of blank white paper to draw your object inside a circle as shown. (You can use your lab manual copy to trace the circle onto the piece of white paper.) The object you draw should be done in pencil. Use black for the outer circle and any other color for the inner circle. The circles don't have to be "perfect". You will have to submit this drawing separately as a hard copy to the class basket. Be sure you put your name on your drawing.

Use the full name of the parts listed on the next page (17) to fill-in the blanks. Do not use capital letters.

Use a lower case "e" and approximate font size 11 or 12. Draw the letter "e" as it appears on the slide. What you see with your eyes before you put it under the microscope. [If easier, you may do this on the white sheet of paper you already used above to draw a specimen.]

Draw what the letter "e" looks like while viewing through the microscope. The "e" should be upright and normal when you place it on your slide and under the lens. Be sure the "e" is lower case and about font size 11 or 12. [Again, if it is easier, you can draw this on your white sheet of paper. ]

You do not have to do the "Explain" on #4 under Observation: Invresion.

the outside layer around a cell

the area where DNA is stored in eukaryote cells

the clear watery fluid that fills cells and facilitates transportation of food, etc, inside the cell

You will get a sample of "pond" water and locate a moving microorganism instead of using a Euglena culture.
