Multiple Choice
Write the letter that best answers the question or completes the statement on the line provided.
_____ 1. An advantage of sexual reproduction over asexual reproduction is that sexual reproduction
a. takes less time.
c. provides genetic diversity.
b. requires more time.
d. produces identical offspring.
_____ 2. Which is one advantage of having a cell’s DNA bundled into separate chromosomes?
a. During DNA replication, the number of chromosomes is cut in half.
b. During DNA replication, the number of chromosomes stays the same.
c. During cell division, each daughter cell will get the same number of genes.
d. During cell division, each daughter cell will get a random number of genes.
_____ 3. When during the cell cycle are chromosomes visible?
a. only during interphase
b. only when replicating
c. only during cell division
d. only during the G1 phase
_____ 4. Which event occurs during interphase?
a. The cytoplasm divides.
c. Spindle fibers begin to form.
b. Centrioles duplicate.

play in mitosis?
a. replicate DNA
b. increase cell volume
c. connect to spindle fibers
d. dissolve nuclear envelope

parent cell that has four chromosomes will
produce two daughter cells, each containing

Animal Cell
Figure 10–1
_____ 7. One difference between cell division in plant cells and in animal cells is that plant cells have
a. centrioles.
c. a cell plate.
b. centromeres.
d. chromatin.
_____ 8. When cells are grown in a laboratory, which factor can stop normal cells from dividing?
a. contact with other cells
c. a cut in the skin
b. growth factors
d. injection of cyclin
_____ 9. Cells grown in a petri dish tend to divide until they form a thin layer covering the bottom of the dish. If
cells are removed from the middle of the dish, the cells divide until they fill the empty space. What does
this experiment show?
a. Cell division is a completely random process.
b. Once cells divide, they can never divide again.
c. The controls on cell growth and division can be turned on and off.
d. There is only a limited amount of DNA available to a given group of cells.

d. multicellular and unicellular organisms.
_____ 14. The rate at which wastes are produced by a cell partially depends on the cell’s
a. ratio of surface area to volume. c. volume.
b. type of membrane.
d. surface area.
_____ 15. When during the cell cycle is a cell’s DNA replicated?
a. G1 phase
c. S phase
b. G2 phase
d. M phase
Modified True/False
Indicate whether the statement is true or false. If false, change the underlined word or phrase to make the statement
true.
_____ 16. The structure shown in Figure 10–2 is a replicated
chromosome.
_____ 17. In eukaryotes, the spindle breaks down during prophase
and re-forms during telophase.
Completion
Complete each statement on the line provided.
18. A cell with 5 chromosomes in the G1 phase will have
19. Look at Figure 10–3. Once structure A has completely
formed, another phase of the cell cycle will start. This
phase will be called
.
20. During normal development, the cells between
toes and fingers die by
,
a process of programmed cell death.
Short Answer
write the answers to the questions on the lines provided.
23. List two problems that growth causes for cells.
Figure 10–2
chromatids in the G2 phase.
24. Which type of reproduction, sexual or asexual, is best suited for organisms that live in a place where
environmental conditions are stable? Explain.
25. The level of cyclins in a cell increases during the M phase of the cell cycle. What might happen to a cell if no
cyclins were present during the M phase?
Using Science Skills
Use the diagram below to answer the following
questions on the lines provided.
Figure 10–4
26. Interpret Visuals Look at Figure 10–4. Which diagram shows cancer cells? How do you know?
27. Compare and Contrast Explain how cancer cells are different from normal cells. Then, relate these
characteristics to the diagram in Figure 10–4 that shows cancer cells.
28. Predict Look at the cancer cells shown in Figure 10–4. What can happen if these cells are left untreated?
30. Problem Solving How might the cancer cells shown in Figure 10–4 be prevented from doing more harm to the
organism they are a part of?
31. Relate ratio of surface area to volume to cell growth and cell division.
32. List and describe the main events of the cell cycle (Interphase, mitosis, cytokinesis). Illustrate your description
with a diagram of a cell with four chromosomes going through the cell cycle.
33. Discuss the relationship between mitosis and cytokinesis. What would be the result if one happened without the
other?
