Mitosis introduction
- 1. The Life Cycle of a Cell The Cell Cycle and Mitosis
- 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. The Cell Cycle A cell spends most of it’s life in what part of the cell cycle?
- 4. Mitosis- making a new nucleus, then a new cell
- 6. Chromatids Cell Wall Cytoplasm
- 7. Interphase
- 8. What phase is the cell shown in? Prophase The original and duplicate strands of DNA are called sister…. Chromatids What disappears during prophase? Nuclear membrane, nucleolus
- 9. What phase is the cell shown in? Metaphase Where are the chromatids located during metaphase? Middle What’s another name for the center or middle of the cell? Equator
- 10. What phase is the cell shown in? Anaphase What attaches the chromatids to the spindle fibers? Centromere
- 11. Cell plate What phase is the cell shown in? Telophase What reappears in this phase? Nuclear membrane, nucleolus
- 12. How does cytokinesis differ in this cell from the one shown in the previous slide?
- 13. What are the two organelles (circled in red) that migrated to opposite poles of the cell during prophase called? Centrioles What role do these organelles play in cell division? They form the spindle apparatus
- 14. What do we call the two cells formed from mitosis? Daughter cells
- 15. What are the three parts of G1 Synthesis interphase called? G2 What happens to the DNA during the synthesis stage? Duplication
- 16. Why do we duplicate the DNA during interphase? So that the daughter cells have the same information as the mother cell!
