  1. Cell Cycle Mrs. Hertel

  2. Define the cell cycle and state the order of its steps. • Define and identify the different phases of mitosis. Objectives

  3. All living things go through cycles. Likewise, your cells go through the cell cycle. • The cell cycle is a series of stages your cells go through. • There are three stages to the cell cycle: • Interphase, mitosis, and cytokinesis Cells come from other cells…

  4. Interphase • During interphase • This is all done Interphase

  5. Mitosis is • Did you notice that mitosis has nothing to do with cell division? • Again: Mitosis

  6. Cytokinesis Cytokinesis

  7. When any nucleus divides, • A chromosome • Chromosomes • Half Mitosis: four phases

  8. 1: DNA; 2: Chromatin; 3: Chromatid; 4/5: Chromosome

  9. Pairs of chromatids • Nucleus and nucleolus • Centrioles • Spindle Prophase

  10. Prophase

  11. Chromosomes • Spindle fibers Metaphase

  12. Metaphase

  13. Chromatid • Chromatids Anaphase

  14. Anaphase

  15. Spindle fibers • Chromatid • Nucleus • Cell Telophase

  16. Telophase

  17. After the four phases of mitosis, Mitosis

  18. After mitosis occurs, • Remember, • For animal cells, Cytokinesis is cell division

  19. Cytokinesis

  20. In plant cells, • In plant cells, • As time goes on, Plants

  21. Cell Plate

  22. Three important things to remember: • 1. Mitosis • 2. Mitosis • 3. After Wrap Up! http://www.7bscience.com/uploads/4/7/3/3/473362/cell_cycle_slides.pdf
