Mitosis introduction

  1. 1. The Life Cycle of a CellThe Cell Cycle and Mitosis
  2. 2. Are all cells doing the same thing at the same time?Find examples of cells that look like they are doing something different.
  3. 3. The Cell CycleA cell spends most of it’s life in what part of the cell cycle?
  4. 4. Mitosis- making a new nucleus, then a new cell
  5. 5. Steps of Mitosis
  6. 6. Chromatids Cell WallCytoplasm
  7. 7. Interphase
  8. 8. What phase is the cell shown in? ProphaseThe original and duplicate strandsof DNA are called sister…. ChromatidsWhat disappears during prophase? Nuclear membrane, nucleolus
  9. 9. What phase is the cell shown in? MetaphaseWhere are the chromatids locatedduring metaphase? MiddleWhat’s another name for the center ormiddle of the cell? Equator
  10. 10. What phase is the cell shown in? AnaphaseWhat attaches the chromatids tothe spindle fibers? Centromere
  11. 11. Cell plateWhat phase is the cell shown in? TelophaseWhat reappears in this phase? Nuclear membrane, nucleolus
  12. 12. How does cytokinesis differ in this cell from theone shown in the previous slide?
  13. 13. What are the two organelles (circled inred) that migrated to opposite poles ofthe cell during prophase called? CentriolesWhat role do these organelles play in celldivision? They form the spindle apparatus
  14. 14. What do we call the two cells formed frommitosis? Daughter cells
  15. 15. What are the three parts of G1 Synthesisinterphase called? G2 What happens to the DNA during the synthesis stage? Duplication
  16. 16. Why do we duplicate the DNA during interphase? So that the daughter cells have the same information as the mother cell!
