Vocabulary
Look for terms in the glossary and within the chapter; index may be helpful here. If you go to a website make
sure you are getting a biology or science definition!
You should do vocabulary how ever you will really use it – Quizlet, apps, flashcards, handwritten, typed, etc.

* Vocabulary will be checked on Wednesday May 14, 2014 when we have our first genetics quiz. *
Chapter 10.1
* This is due on Monday 5/12/14 *
You might need to complete these on notebook paper or a word document. You can put answers on this page if
you feel you have enough room. Please use complete sentences unless it specifically say “list”.
1. What is important about the surface area: volume ration of a cell?
2. What are some reasons cells divide?
3. What are some reasons organisms make new cells?
4. Define DNA
5. Explain how DNA is packaged.
6. How does a (eukaryotic) cell prepare to divide?
7. What is the difference between a gene and a chromosome?
8. Compare and contrast a eukaryotic chromosome to a prokaryotic chromosome.
9. Explain prokaryotic (bacterial) cell division
10. Why are daughter cells identical?
11. Imagine that you are observing a cell that divides once every hour for 12 hours. Assume that
none of the cells die during this period (have a life span longer than 12 hours). How many cells
would exist after each hour? How many cells would there be at the end of the 12 hours?
Chapter 10.2 * This is due on Thursday 5/15/14 *
12. List the phases of the cell cycle
13. List the stages of mitosis (which is a part of the cell cycle)
14. For each stage of mitosis list the events that occur
15. For each stage of mitosis list the structures or organelles that are being seen or used by the cell
16. Why don’t we easily see chromosomes during interphase?
17. Why does mitosis only happen in eukaryotic cells and not prokaryotic cells?
18. What is cytokinesis?
19. What is a cell plate?
20. Compare and contrast animal cytokinesis to plant cytokinesis
21. Why does the number of chromosomes not constantly increase?
Chapter 10.3 * This is ALSO due on Thursday 5/15/14 *
22. What factors influence cell growth and division?
23. Why would the environment be a factor that influences growth and division of cells?
24. Define feedback
25. Define inhibition
26. What is feedback inhibition as it relates to cell division?
27. Describe G1, S and G2
28. What is G0
29. Complete the following graph using the data table on page 240. There is graph paper on the
back of this sheet.
Answer the questions based on your completed graph and the information on page 240.
a. What is the independent variable in this experiment?
b. Identify the dependent variable in this experiment.
c. Describe what happens to yeast cell colonies when they are exposed to UV light. UV
means ultra violet.
