Study Guide – Mitosis / Meiosis Unit Test

Biology

Using your own sheet of paper, respond to the following questions. This assignment is due on Monday, March 17 (1^st / 7^th period) or Tuesday, March 18 (4^th period).

1. For the following diploid cell with three chromosomes, illustrate the indicated phases of mitosis. The size of the chromosome represents the chromosome number (the largest chromosome is #1; the second largest is #2; the smallest is #3) and the color indicates the parental origin (black is from mom, blue is from pop):

Prophase:
Metaphase:
Anaphase:
Telophase:

2. For the following diploid cell with three chromosomes, illustrate the end products of stage 1 and stage 2 of meiosis. The size of the chromosome represents the chromosome number (the largest chromosome is #1; the second largest is #2; the smallest is #3) and the color indicates the parental origin (black is from mom, blue is from pop):

Parent Cell:
Stage 1:
Stage 2:

3. For mitosis, when does DNA replication occur?

4. For meiosis, when does DNA replication occur?

5. How many daughter cells are produced during a mitotic cell division?

6. How many daughter cells are produced during a meiotic cell division?

7. Describe the genetic relationship as either “identical” or “not identical” between:

a) The parent cell and the daughter cells of a mitotic cell division

b) The parent cell and the daughter cells of stage 1 during a meiotic cell division

c) The parent cell and the daughter cells of stage 2 during a meiotic cell division

d) The two daughter cells of stage 1 during a meiotic cell division

e) The four daughter cells of stage 2 during a meiotic cell division (compare all the cells to each other)

8. What is the main purpose of a mitotic cell division? In other words, when is mitosis needed by organisms?

9. What is the main purpose of a meiotic cell division? In other words, what is the ultimate function of the cells that an organism produces during meiosis?
