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?

3. Visual Literacy: Re-create the normal cell cycle regulators (pg. 253). Include: Cyclin, CDK and checkpoints. Think-Pair-Share the following question: What does a stop light signal mean to you? After creating Figure 9.11, write one sentence under your diagram on how proteins and enzymes are similar to stop-light signals.

4. Apoptosis: Reviewed programmed cell-death. Completed sections on reading guide.

Chapter Nine: The Cell Cycle

This week in Biology we have been studying Mitosis. We have observed prepared slides of the root tips of Allium cepa (onion), and next week slides of Ascarcis lumbricoides and Fish (species unknown). We have also been estimating the time that a cell spends in each phase of the cell cycle. Counting the total cells in a field of view, we determined the total number of cells, and then tallied the number of cells in each phase. With this data we are calculating the what percentage each stage is of the total: Interphase, prophase, metaphase, anaphase and telophase.

The above photomicrograph was taken by an inquisitive student.

This Weeks Projects:

(1)Recreating diagrams of the cell cycle.

(2)Vocabulary Fold-ables for 9.1. Including word, definition and symbol.

(3)Reading Guide 9.1-9.2

(4)Final Abstract and Graph for Rates of Diffusion & Surface Area:Volume using Gelatin Cells.

Our focus this week has been on Mitosis in Plant and Animal Cells. Students examined prepared specimens of Allium cepa (onion) and Ascarcis lumb

Surface Area and Volume: February 7-8, 2012

Goal: Examine the affects of SA/V on diffusion rates of cells.

Daily Syllabus:

1.Bell Quiz:

Match the Following Vocabulary to the correct description.

CELL CYCLE, INTERPHASE MITOSIS

a. The period in which the cell is not dividing________.

b. The process of nuclear division________________.

c. The sequence of events in the life of a eukaryotic cell_________.

2. Review SA/V Math Questions from lab sheet.

3.Lab: Diffusion & Surface Area/Volume in Artificial Cells

Simulations of diffusion rates in cells are reproduced using ‘gelatin’ cells and phenol red-dye in distilled water. After placing the different sizes of gelatin cells in the dye mixture for the appropriate times, measure the rates of diffusion in (mm), using a centimeter ruler. Fill in the chart with your data, and the appropriate units.
