Cell division (Bio Unit 3.5)

Welcome back from holiday break! I hope you lived well or at least helped others do so. We’re doing a short unit on cell division before diving into one of our biggest and deepest units yet: Genetics. Take a look at the gif of mitotic cell division above. When you think about that fact that this complex process happens constantly, automatically, without major errors, literally trillions of times over in your body, it truly is an amazing feat of biology. These cells have their Nuclei, DNA, and chromosomes labeled red, while cytoskeletal fibers are labeled green.

Tasks for this mini-unit:

  1. Observe and sketch cells undergoing mitosis under the microscope.
  2. Learn and take notes about mitosis by creating a graphic organizer.
  3. Read and complete textbook questions (canvas).
    1. Enriched – These end of lesson questions (1-5; 1-7; 1-6)
    2. Honors – All end of lesson questions (1-10; 1-9, 1-11)
  4. Make sure you’ve read and participated in the “three person babies” discussion (canvas).
  5. Go deeper
    1. Compare and contrast the processes of Mitosis and Meiosis
    2. Understand how the cell cycle is regulated
    3. Describe how cancer arises when the cell cycle goes awry
    4. Read an article about molecular cancer research
  6. Complete a quiz on the cell cycle, mitosis, and meiosis.

Thursday, January 7 update: Below are links to articles we read in class. If you were absent you can find the assignment on canvas. The articles list appears in order of increasing difficulty. If you are a slower or weaker reader, pick an article with a low number. Conversely if you are a strong reader and/or want a challenge, pick a higher number. You will complete and turn in an article note template sheet for your article.

  1. Do textbooks have the cell cycle all wrong?
  2. Drug found in evergreen trees kills cancer.
  3. When this gene fails, cancer may follow.
  4. Cancer research gets a better look at “Zombie Cells.”
  5. New Cell Structure: The “Mesh”
  6. Do sperm have commitment phobia?
  7. How cells know when to stop growing and split.
  8. Are telomeres the key to aging and cancer?
