Splitting Up Into Groups

Mr. Finley is splitting us into different groups.

Group 1: Complete pg. 97

Group 2: At the front reviewing worksheet and look at cells.

Group 3: Completing simulation and taking notes. - 1. go to cellsalive.com 2. click on mitosis 3. write important steps for each stage write key terms

I am in group 1 right now...

1) How long does the growth phase of the cell cycle take?

2)How much time does the cell cycle spend in Interphase?

3)What total length of time it takes for the skin cell to complete 1 full cell cycle?

4) What phase of the cell cycle takes about 8 hours?

5)Suppose another type of skin cell takes 44 hours to complete one cell cycle. If all of the phases are proportional to the length of time shown in the diagram, how long will the preperation for the cell division phase last?

6) According to the diagram, what is the 2nd stage of mitosis?

Answer Key:

1) D- 10 hours

2) C- 21 hours

3) D- 22 hours

4) A- DNA Replication

5) B- 6 hours

6) B- Metaphase

7) We can account for these numbers because the cell spends the most time in interphase. So more cells will be in inter[hase. Then since it takes less time for mitosis to happen less cells will be in mitosis.

8) You could use an onion root and put it in different temperatures.

Now I am in group 2...

1) Why would we expect the onion root to be dividing?

We said the onion root would be dividing because it needs to grow so it can gather more water for the plant.

2)What are the dyed objects inside the cell?

Chromosomes.

3) Is there evidence of cellular division?

Yes because you see that the chromosomes are in different phases and in different places and that means that they are going through the different cycles and in the different phases they look different.

We didn't finish all of it so the other info on the other group will be posted tomorrow...
