1. Using the letter “e” slide and the 4x (scanning) objectivelens:

1. Using the circle on the right, draw the letter “e”
   exactly as it appears under the 4x objectivelens.

Note that you can snap a photo with asmartphone
or take a screenshot of your computer screen of
the 4x image instead of drawing it here. Label the
photograph as “3a” and include it with your submitted
work if you choose to use this method.

1. What is the total magnification of the image?

1. How is the orientation of the letter “e” as seen through themicroscope different from the way an “e” normally appears?

1. If the letter “e” is not lighted brightly enough or is toobright, what part of the microscope would it be best toadjust?

1. In what direction does the image appear to move when the stageis moved to your left?

1. In what direction does the image appear to move when the stageis moved away from you?

1. Using the letter “e” slide and the low power (10X) objectivelens:

1. How has the image of the letter “e” changed when you switchedfrom the 4X to the 10X objective lens? Could you still see the fullletter “e”?

1. Using the letter “e” slide and the high power (40X) objectivelens:

1. Could you see the entire letter “e” with the 40X objective lensin place?

1. Is your field of view on high power larger or smaller than thefield of view on low power?

1. Using a cheek cell slide:

1. In the circle on the right, draw a picture of
   one cheek cell viewed under high power (40X) and
   label the nucleus, cell membrane, and cytoplasm.

Note that you can snap a photo with asmartphone or
take a screenshot of your computer screen of the 40x
image. Label the photograph as “7a” and include it
with your submitted work if you choose to use this method.

1. Using the onion root tip slide

1. In the circle on the right, draw the cells of
   the onion root tip as you see them under the
   microscope at 40x. Label all the organelles and
   cell structures you can identify.

Note that you can snap a photo with asmartphone
or take a screenshot of your computer screen of
the 40x image. Label the photograph as “7a” and
include this with your submitted work if you choose
to use this method.

1. Using the bacterial cell slide

1. In the circle on the right, draw the cells of
   the bacteria as you see them under the
   microscope at 100x. Label all the organelles and
   cell structures you can identify.

Note that you can snap a photo with asmartphone
or take a screenshot of your computer screen of
the 100x image. Label the photograph as “15a” and
include this with your submitted work if you choose
to use this method.

1. What do prokaryotic cells have instead of a nucleus?

1. Fill in the blanks with one (or more) of these choices:plant cell, animal cell, orbacterial cell. Questions may have more than oneanswer and answers can be used more than once.

1. You observed some cells through a microscope. You did not seeany organelles in these cells.
   

These cells are____________________________________

The cell observed is a_______________________________

1. You saw a cell with a cell wall. Which type(s) of cells wouldnot be a correct identification?

The cell is not a(n) __________________________________

1. Three organelles and/or cell structures that are found in plantcells, but not in animal cells are: ___________________,__________________, and _____________________.

1. The structure where proteins are manufactured is a:____________________.

1. An infertile man has a sperm sample tested and discovered thesperm have low motility (don’t swim normally). The malfunctioningcell structure in these sperm is a:______________________________.

1. Two structures that a material would have to cross to enter thecytoplasm of a plant cell are the ___________________ and the________________________.

1. ______________________ would be more numerous in muscle cellsthan skin cells, due to the higher energy needs muscle cellshave.

1. The ___________________________ is responsible formanufacturing fats (lipids) for use and storage in a cell.

1. The location where genetic information is stored is the:___________________.

1. The location in the cell where most organelles can be found isthe: ________________________________.

1. The ____________________________________ allows some materialsto enter the cell, but not others.
