Mitosis and Cancerous Cells
Introduction
Mitosis is by definition, “A type of cell division that results in two daughter cells each having the same number of chromosomes as the parent nucleus, typical of ordinary tissue growth.” Mitosis is a vital process to living organisms. Without mitosis, organisms could not grow, age, repair, or exist in general. Therefore, it is very important that the cell cycle is carefully controlled by the cell. This refers to is the limits set on cell division to prevent it from growing out of control, which are often special proteins. While it is true that certain cells, skin for example, divide faster than other cells, it is very dangerous for cells divide without limitation. “The uncontrolled growth and division of cells”, is called “Cancer” when cancer occurs it is often deadly the host. More interestingly, the proteins and materials in cells that prevent this almost always stop being produced by the cell, and the cancerous cells become “immortal cells” that will not die. In short, cancerous cells are those that grow without limitation, either touching or not touching other cells. The purpose of this experiment was to find out whether or not cancerous cells had a higher percentage rate of division. As well as to explore the similarities and differences between the cell cycles of normal cells and cancerous cells. To do this, cell tissue cells were observed and their state of division was recorded. The Control of the experiment was normal types of tissue, and the Independent variable was the types of cancerous cells. The Dependant variable was the cells in their different states of mitosis that would possibly change depending on the cancerous, or normal tissues. Hypothesis The percentage of cancer cells dividing was higher than the percentage of normal cells dividing. Materials The materials used in this lab included a high powered microscope, six alternate cancerous/ noncancerous tissue slides, a television, an informational video on cell mitosis, a scientific journal, a calculator, and a data table. Procedures Watch the informational video on the television about cell mitosis. Read the informational section of the journal to learn about cancer. Use the microscope to observe and learn about the stages of mitosis. Discern which cells observed are in what phase. Fill in the data table with the number of cells in their different stages of mitosis. Use the calculator to determine the percentage of cells dividing and the percentage of cells at rest. Observe and discern the stages of mitosis for different cells in all the different types of tissues. Open the journal and answer the three different questions about cancer and cell mitosis.

The cancer cells divide at a much more rapid rate than normal cells, this is the reason why that is so. Regular cells have cancer/ tumor inhibitors built in to stop cells from growing out of control and harming the host. Another difference between regular cells and cancer cells, is that cancer cells don 't die, they are "immortal" and will live on forever basically. Cancer cells will grow even when they come into contact with other cells unlike regular cells which will stop growing. And the most basic difference between regular cells and cancer cells is that the proteins which inhibit rapid cell growth and division are most commonly no longer existent in cancer cells, which explains their rapid growths and …show more content…
This applies to all tissues observed with their cancerous counterparts. Because cancer is basically cells that have lost the ability to control or inhibit cell growth, cancerous tissues have a much higher percentage of cells that are in a state of division than those of the healthy counterparts. This was determined through using a microscope and knowledge of the cell cycle to determine the ratio of nondividing cells, those in interphase, to the number of dividing cells. Since the number was greater in the cancerous tissues than the healthy counterparts, it was concluded that cancerous tissues have a higher number of dividing
