Presentation Transcript

  1. (1) Comparing Mitosis and Meiosis Slide 001

  2. Memory Maker! Mitosis Makes my “toes” Meiosis Makes a new “me” Slide 002

  3. Overall goal! Mitosis Produce identical cells with the same amount of DNA, to replace dying cells or allow growth. Meiosis Produce cells with ½ the original amount of DNA so that offspring can receive traits from each parent. Slide 002

  4. Cells That it Occurs in! Mitosis BODY CELLS (One cell divides once, resulting in two cells) Meiosis REPRODUCTIVE CELLS (One cell divides twice, resulting in 4 cells) Slide 002

  5. Effect on DNA! Meiosis Amount of DNA is cut in ½. (Ex: Original Cell = 46 Chromosomes Daughter Cells = 23 Chromosomes) Mitosis Amount of DNA is the same. (Ex: Original Cell = 46 Chromosomes Daughter Cell = 46 Chromosomes) Slide 002

  6. Interphase – INCREASE!Grab 3 colors – don’t draw until Prophase! Mitosis Meiosis BOTH CELLS BEGIN WITH 3 DIFFERENT CHROMOSOMES Slide 002

  7. Prophase – PAIRS!Grab 3 colors Mitosis Meiosis X X X X X X X X X X X X BOTH CELLS BEGIN WITH 3 DIFFERENT CHROMOSOMES Slide 002

  8. Metaphase - MIDDLE Mitosis Meiosis X X X X X X X X X X X X Slide 002

  9. Anaphase - APART Mitosis Meiosis V V Slide 002

  10. Telophase -TWO Mitosis Meiosis Slide 002

  11. Cytokinesis - CUT Mitosis Meiosis Slide 002
