Biology Test Review Sheet - Introduction to the Cell
Cell 1
Figure 7-1
1. Which organelle breaks down food into particles
the cell can use?
2. If this organelle were to open up the cell would die
because it contains enzymes used to break things
down.

3. Which cell structure contains the cell's genetic
material and controls the cell's activities?
4. Which organelle makes proteins using coded
instructions that come from the nucleus?
5. The structure labeled I in Figure 7-1 is a thin,
flexible barrier around a cell. It is called the
6. Which of the following is a function of the
cytoskeleton?
Figure 7-1
11. Which of the cells in figure 7-1 is eukaryotic?
12. Which of the cells in Figure 7-1 is a plant cell?
13. Which cell in Figure 7-1 would most likely be part
of a squirrel's intestinal tract?
7. Which organelle would you expect to find just in
plant cells?
14. Which of the cells in Figure 7-1 most likely has a
large vacuole?
8. Which organelle converts food into compounds that
the cell uses for growth, development, and
movement?
15. What types of organisms are prokaryotes?
9. Unlike the cell membrane, the cell wall is
10. Prokaryotes lack
22. Diffusion is the movement of molecules from
___________concentration to ___________
contntration
23. If a cell was placed into a 7% NaCl solution and
and it shriveled up. What could have been the
concentration of salt inside the cell. (remember
SALT SUCKS)
Figure 7-3
16. Organelle A in Figure 7-3 is covered with
ribosomes and helps transport proteins around the
cell. It is called the
24. Which of the following is a function of the cell
membrane?
25. The monomer of carbohydrates are
27. The diffusion of water across a selectively
permeable membrane is called
28. When enzymes get to hot or cold they lose their
shape, this is called.
29. Which means of particle transport requires input of
energy from the cell?
30. An animal cell that is surrounded by fresh water
will burst because the osmotic pressure causes
Homer notices that his
shower is covered in a strange green slime. His
friend Barney tells him that coconut juice will get
rid of the green slime. Homer decides to check this
out by spraying half of the shower with coconut
juice. He sprays the other half of the shower with
water. After 3 days of "treatment" there is no
change in the appearance of the green slime on
either side of the shower.
17. What is the independent variable in Homer's
experiment?
18. What is the dependant variable for the Homer
experiment
19. True or false? Polymers are used to build
monomers
Figure 7-2
31. Which organelle in Figure 7-2 is much larger in
plant cells because they need to store more water
than most animal cells?
32. Organelle E in figure 7-2 converts the sun's energy
into energy for the cell in the form of glucose.
20. Which organelles help provide cells with energy?
21. 46.31km = ___________m?
33.
Which of the following contains a nucleus?
a. prokaryotes
b. bacteria
c. eukaryotes
d. organelles
34. Looking at Figure 7-4, what type of solution is the cell
in?
35. Looking at figure 7-4, what will eventually happen to
the cell?
36. The main function of the cell wall is to
37. The cell membrane contains channels and pumps that
help move materials from one side to the other. What are these
channels and pumps made of?
38. A substance with a pH of 6 is called
39. When salt is dissolved in water, water is the

40. What structures allows the cell to maintain homeostasis by separating it from its environment?
41. How were the "smelly balloons" that we used in
class a good example of a membrane being
selectively permeable?
42. Compare prokaryotes with eukaryotes. Give an
example of each type of cell.
