pg 68 - 2 ptsIn addition to the questions on this page, each of you will do a
search for chromosome number of an organism and report the number on this page.
Question 4
4.
From pg 68, Whitefish Blastula Slide, complete #2 by identifying the phase of
mitosis - 4 pts
Question 5
5.
pg 69 - 5 pgsWrite the name of the phase beneath each drawing in Figure 7.5
Practice identifying the phases of mitosis in the root tip of an onion,
Onion root tip image to use in completing Table 1
Question 6
6.
Table 1 - 17 ptsUse the image of the root tip above to complete
Time for 100% is given ( about 15 hrs interphase=900 mins + about 83 mins
mitosis = 983 mins) Note: Your counts may not match this time exactly because
you are only counting a small portion of the root tip.
Question 7
7.
pg 70 - 7 pts
pg 71 - no Qs - need beads to manipulate
Be sure you can step through the beading exercise to demonstrate mitosis and
meiosis as you will be asked to demonstrate it for 30 lab skill points.
Question 8
8.
pg 72 - 12 pts
Question 9
9.
pg 73 - 11 pts
If you feel good about your ability to distinguish between the processes of
mitosis and meiosis with the beads, this might be a good time to ask about being
graded on this skill (30 pts).
