Cell Division / Cellular Reproduction

The purpose of this lab is to assist you in learning about cellular division which includes the cell cycle and mitosis. You will learn how the process is supposed to take place in normal cells then how the process is altered in cancerous cells.

You will go to the following website: http://glencoe.mcgraw-hill.com/sites/dl/free/0078757134/383933/BL_23.html

You will follow the instructions and work through the simulation as instructed in the lab.

As you perform the simulation, you will record your results in the table below (in another color font). 

Once you have completed the lab activity and the table, you will answer the remaining journal questions below. Please be sure to confer with your textbook and lecture notes.  Please answer all questions in another color font.

Save your file as .doc or .docx and upload it into eCampus in the proper lab section for grading. Do NOT copy and paste it into the text box on eCampus.

Number of cells in each phase of cell cycle

 

Interphase

Prophase

Metaphase

Anaphase

Telophase

% of cells dividing

% of cells at rest

Normal lung

 

 

 

 

 

 

 

Cancerous lung

 

 

 

 

 

 

 

Normal stomach

 

 

 

 

 

 

 

Cancerous stomach

 

 

 

 

 

 

 

Normal ovary

 

 

 

 

 

 

 

Cancerous ovary

 

 

 

 

 

 

 

%cells dividing = PMAT/total cells;    % cells at rest = interphase/total cells

 

Journal Questions:

1. What are the 3 phases that occur during interphase. Explain each stage.

 

 

1. List 2 distinguishing characteristics of each stage of the cell cycle (Interphase, prophase, metaphase, anaphase, & telophase).

 

 

1. Based on your data and observations, what are some of the differences between normal cells and cancer cells?

 

1. Which type of cancer shows the most aggressive growth? Explain.
