Mitosis & Meiosis Free Response

Slide 2 / 7

1 Mitosis and Meiosis are two distinct types of eukaryotic cellular reproduction. Compare and contrast them by responding to the prompts below:

A

When a cell undergoes mitosis, how many cells are produced and how does their chromosome number compare to the parent cell?

B

When a cell undergoes meiosis, how many cells are produced and how does their chromosome number compare to the parent cell?

C List three reasons why a eukaryotic cell might undergo

mitosis.

D Why would a eukaryotic organism produce cells via

meiosis?

2 Compare and contrast cancer cells and “normal” cells by responding to the prompts below:

A Describe the primary difference between cellular

reproduction in cancer cells and in non-cancerous cells.

B What do tumors consist of and what are the specific

differences between malignant and benign tumors?

Slide 4 / 7

3 Compare and contrast the two primary methods

• f cancer treatment by responding to the prompts

below.

A

Radiation therapy is non-systemic but chemotherapy is

• systemic. Explain the difference between systemic and

non-systemic.

B

Chemotherapy typically targets which structure found in the process of mitosis? How would the destruction of this structure affect mitosis?

C Radiation typically targets which structure found in cells?

How would this affect mitosis?

4 Below is an image that represents the chromosomes found within a human cell. Use this image to respond to the prompts below.

A Is this the karyotype of a human somatic cell or a human

gamete? Explain your response.

B Does the karyotype above represent a male or a female?

Explain your response.

C

Does this karyotype demonstrate any chromosomal abnormalities? If so, specify the type of abnormality; if not, why not?

5 The image below illustrates chromosomes during metaphase 1. The darker Xs represent the chromosomes from the mother, while the lighter Xs represents the chromosomes from the father. Use this illustration to respond to the prompts below.

A What is the term for this variation in the way that

chromosomes can line up during metaphase 1 of meiosis?

B How does this lead to increased genetic variation in

• ffspring?
