  1. Warm Up How does an asexual organism reproduce? Name the three reasons that a cell divides. What is cellular division? Why is it important that we have cell division?

  2. Science Fair Projects are REALLY late… • Calls home start this weekend. • Notebook Check on FRIDAY • Quiz • Mitosis Agenda

  3. What is mitosis? Mitosis is the process that divides the cell’s nucleus into two, each with a complete set of genetic material from the parent cell. 4 phases

  4. Nucleus: Organelle that is the “command center” of the cell and contains all the genetic information • Surrounded by a Nuclear Membrane • Chromosome: threadlike structure that carries the genes (aka DNA) • In the NUCLEUS Vocabulary Recap

  5. CD is GRREAT!!! Remember the tool? Mitosis is used for….

  6. CD is Cell Division • G is Growth • R is Repair • R is Reproduction CD is GRReat!

  7. Chromosomes condense and the nuclear membrane disappears. Late Prophase Early Prophase 1. Prophase

  8. Chromosomes line up in the center of the cell. 2. Metaphase

  9. Chromosomes separate. Early Anaphase 3. Anaphase Late Anaphase

  10. New nuclei form containing exact copies of the original cell’s DNA. 4. Telophase

  11. The cell pinches in the middle and divides into two daughter cells. Cytokinesis

  13. Prophase • Metaphase • Anaphase • Telophase • ….Cytokinesis PMAT…C

  14. Mitosis is: • Asexual Reproduction? OR • Sexual Reproduction? • Hint: • Asexual--one cell makes two identical offspring • Sexual--two cells make genetically different offspring What do you think?

  15. A student will be bringing around science textbooks. Turn to page C83. • You will also receive a foldable. • Label the top flap, “STAGES of MITOSIS” Mitosis Foldable

  16. You will create five flaps to represent PMAT….C • Use a pencil and two different colored markers from the bins. • When you are done with the markers, please put them back in my box. • Turn your foldables into me! I will return them. Mitosis Foldables

  17. Mitosis is the process that divides the cell’s nucleus into __________. • A. 3 • B. 2 • C. 1 • D. 4 • List out the different stages of mitosis in correct order. • Explain what happens in Anaphase. Exit Ticket
