Cell Cycle Mitosis (Day 2)

This lesson focuses on the process of mitosis and the number of chromosomes required for cell division. Students will create foldables to visualize the structures involved and understand the differences between parent and gamete cells.

Presentation Transcript

  1. Cell Cycle Mitosis (Day 2) March 4, 2015

  2. March 04, 2015 AIM how does a cell go through mitosis? from mom DO NOW from dad Humans have 46 chromosomes in their body cells – 23PAIRS, one from mom one from dad. If a body cell is about to go through mitosis how many chromosomes total does the cell need before it can divide? 2n n = copy number of chromosome LOWER CASE!!!

  3. Knowing this… How would you describe the copy number of a gamete cell? n 2n n = copy number of chromosome LOWER CASE!!!

  4. Chromosomes from mom Chromosomes from dad Sister Chromatid pair

  5. PARENT CELL IDENTICAL DAUGHTER CELLS

  6. FOLDABLES • TODAY – YOU MUST FINISHYOUR FOLDABLES. I will stamp completed ones for a completion grade. • In your pictures make sure to include labels for the structures: chromosome, sister chromatid, sister chromatid pair, centriole, spindle fibers, cellular membrane, nuclear membrane • If you finish early use your foldable to answer questions on the worksheet (will be homework if do not finish in class)

  7. Wrap up • Name all the phases of mitosis in order. • Are both daughter cells of the parent cell identical to the parent cell? • What is the difference between parent cell and gamete (sex) cell?
