Chromosome Segregation in Mitosis and Meiosis Modeling Mitosis (4 points)
Model out the phases of the cell cycle using the Play-Doh or other modeling material. Take an image of each phase that you can assemble into a single picture at the end of the exercise. Use a different color Play-Doh for each component listed below. Label and keep track of the following cell components:
1. 2 homologous chromosomes
2. Centrosomes
3. Microtubules
4. Centromeres
5. Cell membrane
6. Nuclear membrane
Once you have images of each phase, assemble the images into a single slide to show the progression of your model.
Modeling Meiosis (4 points)
Model out the phases of the meiosis using Play-Doh or other modeling material. If you don’t have any, draw the process. Take an image of each phase that you can assemble into a single picture at the end of the exercise. Use a different color Play-Doh for each component listed below. Label and keep track of the following cell components:
1. 2 homologous chromosomes
2. Centrosomes
3. Microtubules
4. Centromeres
5. Cell membrane
6. Nuclear membrane
Once you have images of each phase, assemble the images into a single slide to show the progression of your model.

Mitosis vs. Meiosis (4 points)
Each image below can be assigned to either mitosis OR meiosis. The images depict 1 pair of homologous chromosomes. Print the cards, cut them out, and arrange them in order. You’ll have two “pathways” when you are done: one that depicts mitosis and one that depicts meiosis. Note: Not all phases of mitosis and meiosis are pictured.
On the next page there are terms or statements that apply to either mitosis or meiosis. Sort those out into a mitosis group and a meiosis group.
When you are finished with the sorting exercise, take a picture of the sorted cards.
2
Involves a reduction in the number of chromosomes
Part of sexual reproduction
Crossing over occurs
Involves Interphase, Prophase, Metaphase, Anaphase, Telophase, and Cytokinesis
Daughter cells are 2N
Produces Gametes
Chromosome number of each daughter cell is the same as parent cell
Daughter cells are haploid
Part of asexual reproduction
Involves Interphase, Prophase I, Metaphase I, Anaphase I, Telophase I, Cytokinesis, Prophase II, Metaphase II, Anaphase II, Telophase II, and Cytokinesis
Tetrads are formed
Daughter cells are N
Daughter cells are diploid
Leads to greater genetic diversity in offspring
