Mitosis and Meiosis

Vocabulary of Mitosis Cell Cycle – Series of events that cells go through as they grow and divide

Mitosis (asexual) – Part of eukaryotic cell division during which the nucleus

divides

Meiosis (sexual) – Process where the number of chromosomes in a cell is cut in

half

Meiosis MitosisNumber of Divisions:

2 nuclear and 2 cytoplasmic divisions1 division of the nucleus and 1 Cytokinesis

Steps:Prophase I, Metaphase I, Anaphase I, Telophase I, Prophase II, Metaphase II, Anaphase II and Telophase II.

Prophase, Metaphase, Anaphase, Telophase and Cytokinesis

Occurs in: Eukaryotes all organisms

Produces: four haploid daughter cells two diploid daughter cells

Genetically: different identical

Definition:

Cellular reproduction where the number of chromosomes is reduced by half through the separation of homologous chromosomes in a diploid cell.

Asexual reproduction where cell divides in two producing a replica with an equal number of chromosomes

Chromosome Number:

Reduced by half Remains the same

Function: sexual reproductionCellular (asexual) Reproduction; general growth and repair of the body

Type of Reproduction:

Sexual Asexual

Creates: Sex cells -Female egg cells Male sperm cellsMakes everything other than sex cells (Somatic Cells)

Number of Cells produced:

4 2

Vocabulary of Mitosis Cell Cycle – Series of events that cells go through as they grow and divide

Mitosis (asexual) – Part of eukaryotic cell division during which the nucleus

divides

Meiosis (sexual) – Process where the number of chromosomes in a cell is cut in

half

Interphase – Period of growth and cell operations

Prophase – Genetic material unravels

Metaphase – Genetic material lines up in the middle of the cell

Anaphase – Genetic material moves to either side of the cell

Telophase – Genetic material forms new nucleii

Cytokinesis – Cells separate

Place the phases in order from Longest to Shortest

Which of the five phases takes the longest period of time?

What do you think the cell does during that phase?

Cancer – Mitosis Gone Wrong Study Sheet

Read the Cancer- Mitosis Gone Wrong reading. Then answer these questions to keep

as a study guide for yourself.

1. Cancer is when what cell process is uncontrolled?

2. Normal cells of the body spend most of their time in which phase of mitosis?

3. List the 5 ways that cancer cells are different than normal cells of the body.

4. How do you end up dying from cancer? Explain how the body loses energy due to

cancer in the space below.

5. List the different possible causes of cancer given in the reading.

6. All of these causes increase the likelihood of cells becoming ________________,

which means that cells may not repair and follow a proper cell division cycle.

7. A tumor is defined as

8. Compare the two types of tumors

9. How is cancer treated?

10. In order to determine if a tumor is cancerous, a doctor will take a

______________________ of it. Describe in the space below what is done

during this procedure and why.

11. If a tumor is deemed cancerous, then one could do a variety of treatments.

For each treatment, state what is done to treat the tumor:

Surgery –

Chemotherapy –

Radiation Treatment –

Analysis

1. Anything that the cell takes in (oxygen, water, food) or lets out (carbon dioxide, waste)

passes through the cell membrane. Which measurement of your model be represents the

surface area of the cell membrane?

2. Everything inside of the cell, including organelles and cytoplasm, uses food and oxygen

and produces waste. Which measurement of your model best represents the total contents

of the cell?

3. As the cell grows larger and accumulates more contents, will it need more or less cell

membrane to survive? Explain your answer.

4. As a cell grows larger, what happens to its surface area to volume ratio?

Analysis

5. As a cell grows larger, what happens to its surface area to mass ratio?

6. Which cell model has the greatest surface area to volume and surface area to mass ratios?

7. Why do cells not survive when the surface area to volume and surface area to mass ratios

become too small?

8. Which cell model has the best chance of surviving?

9. How could the surface area to volume ratio be increased for a large cell?
