You might want to actually write your answers in Word (so you can spell check them) and then cut-and-paste into the boxes. That way, if the computer misplaces your work you can just re-paste the answers.

TAB OR USE THE MOUSE Between the fields....

Answer the questions as best you can. The boxes will expand as you type if you need more space. (Don't worry if it is a one word answer. The box size is standard.)

Since you will be working in groups, put all the names of the people in the group in the box. The ideal group size is 2. As an exception I will allow groups of 3. No groups of 4 or 5. If you work as a group of 3 I expect better answers. Group sizes above 3 will be penalized in the grading.  Anyway, there is no place to put more names!

Name(s):

You are encouraged to work in pairs

1 Name:   IDNumber:

2 Name:   IDNumber:

Your answers will have to be perfect for a group size of 3 not to cost you in the grading. No groups larger than 3 will be accepted.

3-Name:   IDNumber:

Class Period 

This is a relatively long assignment (there are many blanks). Pace yourself, but don’t get distracted. There is more to do besides just reading the tutorials.

You are encouraged, but not required to work in pairs. If you do not "submit" it electronically, I won't get the work!

 1-Go to the Arizona Biology Cell Biology Education site:

 The Biology Project: Cell Biology  This will work best if you open it in a new windows-just clicking should do it, but if not, try opening a second tab (Ctrl-N) and following the link from only one window.

 2-Within this site you will do several things. Please note that this site is intended for college students, and may include vocabulary you will have trouble with. Do not hesitate to ask for definitions.

 3-Click on “Cell Cycle and Mitosis”

4-Using the “next” command at the bottom of each screen go through the 3 modules in this section (DNA Basics, The Cell Cycle, Mitosis). Don’t bother with the mitosis animation-it doesn’t always play well on these machines.

5-Answer the following questions:

Q-1: Define Chromatin:

-No answer-

Q-2What does the G stand for in G1 and G2?

-No answer-

 Q-3 Describe the stages of mitosis in words. You should have one sentence for each stage (that is a minimum of 5 sentences. Don't just cut and paste. I know the standard descriptions. Explaining in your own words will convince me you understand. (THIS IS THE BULK OF THE GRADE!)

-No answer-

6-Go back to the Cell Biology Page and in the left hand column there is an activity: Onion Root Tips. Click on that.

7-Read and follow the “next” until you get to the table, which I have copied below  for you.

After you carry out the on-line onion root tip lab, record your data in this table.

-No answer-
