Mitosis Mini-Exam and Summary

February 23-24, 2012



Academic Goal: Assessment and Summary of Mitosis Chapter 9. Life's Greatest Miracle: How Cells Divide.

Today in class we took a multiple choice, and short answer mini-test on Chapter 9. Questions on the lab practicum only included the Allium cepa, Onion Cell Mitosis Lab. If you missed this examination you will need to take the exam within the week you return to school.

Homework Due Today: February 23 (1,3, 4) & 24 (5, 7, 8), 2012

(1)Flowchart Figure 10.1.
(2)Comparison of Mitosis and Meiosis Table: The Seven Main Elements (Figure 10.1)


Projects Due Monday (1, 3, 5) and Tuesday (5, 7, 8): February 27-28, 2012

(1). Summary and Chapter Nine Portfolio:

Chapter 9 – Mitosis Portfolio

40 points

Your portfolio needs to include the following assignments that you have already completed and your summary about Chapter 9:

1. Your summary must answer the following questions: Two paragraphs minimum: How does mitosis contribute to little elephants becoming big elephants? What are three reasons why cells undergo mitosis? How does cancer cell growth differ from regular mitosis growth? How do cyclins (protein), and CDK (enzyme) regulate the cell cycle. HINT: Consider the traffic-signal metaphor. What portion of Mitosis unit and its labs will be the most memorable for you, and why?

2. Onion Mitosis Lab results

3. SA/V Diffusion Lab Abstract and Graph

4. Foldables: 9.1-9.3

5. Flow Charts: SA/V, Stages of Mitosis and Cell Cycle Regulation

6. Interphase/stages of Mitosis: poem, limerick, haiku or one page essay.

February 21-22, 2012

Academic Goal: Compare and Contrast Meiosis and Mitosis

Today in Biology we are compared and contrasted sexual and asexual reproduction. (Essential Question 2) and also considered how bio-ethical questions are made. We also considered the immeasurable contributions to science and western medicine by Henrietta Lacks.

Standard V: Essential Questions

1. What creates genetic variation in sexually reproducing organisms?
2. Compare and contrast sexual and asexual reproduction.
3. How do mutations positively and negatively affect a species?
4. How are bio-ethical decisions made?

Bell Quiz: Access your text book practice test at biologygmh.com and take the Chapter Nine Practice Test.

Cell Regulation and Cancer

February 17, 2012

Academic Goal: The normal cell cycle is regulated by cyclin proteins. Today we reviewed cell cycle regulation (pg. 253-259) and compared cancer growth rates.

Discovery Questions and Activities: How does cancer growth rates differ from regular cellular division? What do I know about cancer? What do I want to know about cancer? What have I learned about cancer? Review 9.2-9.3 Reading Guide (Due next time class meets), Complete flow chart on Regular Cell-Cycle Regulation pg. 253.


1. Cancer Cells Video Clip: Answer the questions discussed in this video.

2. Think-Pair-Share: Observe data on mitosis rates from regular chicken stomach and cancerous chicken stomach cells. How do they differ?

Normal chicken stomach cell growth
