The Cell Cycle and Mitosis

Each cell in your body has two copies of your genes, one from your mom, one from your dad. Your entire DNA is contained in every cell nucleus, and when your cells get old, or too large, the cell divides. Your DNA is copied so that the new cell also has a copy of the DNA.

Your cells must be very careful to divide the nucleus and the DNA correctly, so that the two new cells have the correct DNA. This process is called Mitosis.

Your cells usually exist (96% of their lives) in a part of their life cycle called Interphase. During this time the cell grows, copies its DNA for mitosis and does it's normal, everyday thing (making proteins and lipids, breaking down carbohydrates to make ATP, interpreting DNA, and growing). After the cell has grown to a size too large for diffusion and osmosis to be efficient, the cell must divide to reduce it's size and to regenerate itself. This time of the cell's life cycle is called MITOSIS (4% of a cell's life).

If you are working on this unit on your own, I recommend you take a look at several videos on the internet. Mitosis is best understood as an animation.
Please be sure to check out all the other activities available. Any activity listed below and turned in before the test will be accepted for credit, and will help you study for the test.




No, I'm not going to make you write a song, but you could!

Here is a powerpoint I created to use with our mitosis model kit. Although the video links won't work, you can review by looking at the images and finding your own videos on teacher tube or the web. Beware student-made videos, they may contain errors!



Once you have a good idea of what you are looking for in each stage of mitosis, complete this activity where you classify cells in different stages of the cell life cycle. Remember, most (96% of cells) are in interphase, the remaining few will be in prophase, and just a couple will be in metaphase, anaphase and telophase.

Good luck!

When you are finished, print your final tally sheet and hand it in with your data table.

Complete the , while you watch this video. Read the directions carefully first! You will need colored pencils or markers.

Meiosis


Meiosis happens only in the female ovum and male testis. It is cell division to create a cell with only ONE gene for each trait (normal cells have TWO genes for each trait, one from each parent).

When an egg cell is developed, it can only have HALF of the chromosomes necessary for the organism because it will be joined by a sperm cell that also contains HALF of the chromosomes necessary.

This is how new combinations of genes are created in each offspring.
