  1. By Jakey Wakey Artaflakey CELL DIVISION

  2. 3 steps of Interphase • G1- cell growth which makes the cell get bigger. ? ? Interphase

  3. 3 steps of Interphase • G1- cell growth which makes the cell get bigger. ? ? Interphase

  4. Centrioles • 3 steps of Interphase • G1- cell growth which makes the cell get bigger. • S- DNA replication which the DNA copies itself. • G2- Centrioles duplicates. ? ? Interphase DNA Nucleus Nucleolus Nuclear envelope

  5. This is the longest of all the phases. • Chromatin come together to form tight Chromosomes. • Nucleolus and nuclear envelope disappear. ? ? Prophase Chromatin

  6. This is the shortest of all the phases. • Chromosomes line up in the middle of the cell. • Spindle attaches to each chromosome. ? ? Metaphase

  7. This is the shortest of all the phases. • Chromosomes line up in the middle of the cell • Spindle attaches to each chromosome. ? ? Metaphase

  8. Chromosomes are pulled apart. • Chromatids now become individual chromosomes. ? ? Anaphase

  9. Chromosomes are pulled apart. • Chromatids now become individual chromosomes. ? ? Anaphase Sister chromatids

  10. Chromosomes are pulled apart. • Chromatids now become individual chromosomes. ? ? Anaphase Sister chromatids

  11. Chromosomes are pulled apart. • Chromatids now become individual chromosomes. ? ? Anaphase Sister chromatids

  12. Chromosomes are pulled apart. • Chromatids now become individual chromosomes. ? ? Anaphase Sister chromatids

  13. Chromosomes are pulled apart. • Chromatids now become individual chromosomes. ? ? Anaphase Sister chromatids

  14. Chromosomes are pulled apart. • Chromatids now become individual chromosomes. ? ? Anaphase Sister chromatids

  15. Chromosomes are pulled apart. • Chromatids now become individual chromosomes. ? ? Anaphase Sister chromatids

  16. Chromosomes are pulled apart. • Chromatids now become individual chromosomes. ? ? Anaphase Sister chromatids

  17. Chromosomes are pulled apart. • Chromatids now become individual chromosomes. ? ? Anaphase Sister chromatids

  18. Chromosomes are pulled apart. • Chromatids now become individual chromosomes. ? ? Anaphase Sister chromatids

  19. Chromosomes are pulled apart. • Chromatids now become individual chromosomes. ? ? Anaphase Sister chromatids

  20. Chromosomes are pulled apart. • Chromatids now become individual chromosomes. ? ? Anaphase Sister chromatids

  21. Chromosomes are pulled apart. • Chromatids now become individual chromosomes. ? ? Anaphase Sister chromatids

  22. Chromosomes are pulled apart. • Chromatids now become individual chromosomes. ? ? Anaphase Sister chromatids

  23. Nuclear envelope reforms. • Nucleolus reappears. ? ? Telophase

  24. Nuclear envelope reforms. • Nucleolus reappears. ? ? Telophase

  25. Nuclear envelope reforms. • Nucleolus reappears. ? ? Telophase

  26. Nuclear envelope reforms. • Nucleolus reappears. ? ? Telophase

  27. Nuclear envelope reforms. • Nucleolus reappears. • DNA unwinds to form chromatin again. • Spindle breaks apart. ? Spindle fibers ? Telophase

  28. The cell fully pinches in forming a cleavage furrow. • In the end there are two cells that have the exact same DNA. ? Spindle fibers ? Cytokinesis

  29. The cell fully pinches in forming a cleavage furrow. • In the end there are two cells that have the exact same DNA. ? Spindle fibers ? Cytokinesis

  30. The cell fully pinches in forming a cleavage furrow. • In the end there are two cells that have the exact same DNA. ? Spindle fibers ? Cytokinesis

  31. The cell fully pinches in forming a cleavage furrow. • In the end there are two cells that have the exact same DNA. ? Spindle fibers ? Cytokinesis

  38. The cell fully pinches in forming a cleavage furrow. • In the end there are two cells that have the exact same DNA. ? Spindle fibers ? Cytokinesis

  39. Then it repeats that cycle forever.  Cell Division
