    1. Why Do Cells Divide?

    2. Why Do Cells Divide? Efficiency of moving materials into the cell The larger the cell becomes the less efficient it is The volume of the cell increases faster then its surface area Cells that grow too large no longer have enough surface area to take in nutrients and remove waste

    3. Ratio of Surface Area to Volume in Cells

    4. DNA Overload As the cell grows it does not make copies of its DNA If it grows too large the DNA in the cell will not be able to contain the information that needs to be stored

    5. Chromosomes Threadlike structures made up of DNA that coils around proteins. Contains genetic information that is passed form parents to offspring.

    6. Chromatids (Sister) One of two identical parts of a duplicated chromosome

    7. Number of Chromosomes Fruit Flies: 8 Carrots: 20 Humans: 46 Fern: 480 White Ash: 138 Turkey: 82 http://i.pbase.com/u9/dannysmythe/large/4319077.Carrot.jpg http://www.news.wisc.edu/newsphotos/images/fruit_fly_research03_6801.JPGhttp://i.pbase.com/u9/dannysmythe/large/4319077.Carrot.jpg http://www.news.wisc.edu/newsphotos/images/fruit_fly_research03_6801.JPG
