NAME:___________________Pre Mitosis Lab Assignment: Due: Tuesday: Jan 8
*Must be completed in order for you to participate in this lab on
Tuesday—the only exception is if you were absent Today.
A.. Complete Part III of the Cell Cycle Study Guide
B. Read Lab 3A: Mitosis in your Lab Manual and answer the following questions: No Manual—you
may make a copy using mine.
C. BRING YOUR LAB MANUAL TO CLASS TOMORROW.
1. The two kinds on nucleus division are _________________and _______________
2. Division of the cytoplasm is called:___________________________
3. Mitosis typically results in new __________________cells.
_______________ results in the formation of _____________in animals and __________ in plants.
4. In plants, mitosis occurs in specialized tissues called _______________________, which are usually
found in these 2 locations_____________tips, and _____________tips.
5. In this lab, we will be examining __________________cells to determine the relative length of time
spent in the various stages of cell division ( both interphase, and in each of the 4 major stages of mitosis).
The length of the cell cycle in these tissues is approximately_________hours ( 1440 minutes).
How many people will be in each lab group?______________Describe the role of each lab
member:_____________________________________________________________________.
6. Sample Problems :
a) 45out of 100 cells examined were observed to be in Prophase, what percent of the time is spent in
Prophase?_____________%
How many minutes were spent in Prophase:_____________min
b) 5out of 100 cells examined were observed to be in Anaphase, what percent of the time is spent in
Anaphase?_____________%
How many minutes were spent in Anaphase:_____________min
*******If you are having trouble with this assignment, you may want to refer to the
Campbell web site and do the Chapter 12 --Case Studies in the Process of Science
Section: (these is only one Case Study). You may want to complete this Case Study.
(THOUGH THIS CASE STUDY IS NOT MANDATORY), then complete the above
questions.
root tip with some of the mitotic figures marked. A cell in late ANAPHASE is seen at (a), while (b)
indicates a PROPHASE nucleus and (c) an INTERPHASE nucleus that has not yet begun to divide.
METAPHASE figure at (a) and an INTERPHASE cell at (b). Can you find other mitotic figures on this
slide? Circle them.
ANAPHASE cell at the arrow. What stage of mitosis is the cell next to it (left)
exhibiting?________________ In what stage are most of the cells seen here?_______________
THAT’S ALL—THE REST OF THE PICTURES ARE FOR REFERENCE.
