Chapter 10 Review

You must answer in complete sentences!

1. Explain TWO problems that can occur when a cell gets too big.


1. Explain TWO problems that can occur when a cell gets too big.

• DNA overload• Exchange of materials


2. What are the two main events of the cell cycle


2. What are the two main events of the cell cycle

Interphase and Cell Division (M Phase)

You must show all calculations and units!

3. What is the surface of a cube with a length of 4 cm, a width of 4 cm and a height of 4 cm?


3. What is the surface of a cube with a length of 4 cm, a width of 4 cm and a height of 4 cm?

4x4x6 = 96 cm2

You must answer in a complete sentence!

4. Look at the pictures below (chromatin has been stained red). What phase of mitosis is being shown in each picture? Explain how you know.

A B C D


4. Look at the pictures below (chromatin has been stained red). What phase of mitosis is being shown in picture B? Explain how you know.

A = anaphase (pulled apart); B = Metaphase (chromosomes lined up in middle); C = prophase; D =

telophase (two nuclei)

A B C D


5. What is the surface area to volume ratio of a cube with 5 cm sides?


5. What is the surface area to volume ratio of a cube with 5 cm sides?

SA = 5x5x6 = 150 cm2

V = 5x5x5 = 125 cm3

SA:V = 6:5

Draw a pretty picture!6. Draw a picture of a duplicated chromosome and label the centromere and sister chromatids.

7. List the phases of mitosis in order !

Prophase, Metaphase, Anaphase, Telophase (Cytokinesis)


8. Describe what happens in anaphase.


8. Describe what happens in anaphase.

• Sister chromatids are pulled apart to opposite ends of the cell


9. How do the internal and external regulators help the timing of the cycle?


9. How do the internal and external regulators help the timing of the cycle?

Internal – checkpoint inside the cell to regulate when the cell is ready to advance to the next step of the cell cycle

External – speed up or slow down the cell cycle


10. How are cancer cells different than other cells?


10. How are cancer cells different than other cells?

• Cancer cells can not regulate the cell cycle

and divide uncontrollably.

11. Calculate the percent absorption of the cube below.

SHOW YOUR WORK! Don’t forget units!

11. Calculate the percent absorption of the cube below.

Total volume = 2x2x2 = 8 cm3

Uncolored volume = 1x1x1 = 1 cm3; colored = 7 cm3

Percent absorption = 7/8 = 87.5%

12. Draw the circular cell cycle figure (with phase names) from memory. Then check your figure against the one on page 245 in your textbook.
