  1. Cell Division Notes Gallery

  2. Station 1 – Interphase Description: A period of growth in which a cell can spend 90% of its time. This part of the cycle is divided into three phases: G1, S, and G2. Cell Division - Notes Gallery

  3. Station 1 – Interphase Plant cell Cell Division - Notes Gallery

  4. Station 1 – Interphase Animal cell Cell Division - Notes Gallery

  5. Station 1 – Interphase Chromatin is a mass of genetic material composed of DNA and proteins that eventually condenses to form chromosomes Cell Division - Notes Gallery

  6. Station 2 – G1 (Gap 1) Description: A period of activity in which cells do most of their growing. Cells increase in size and synthesize new proteins and organelles. The G1 checkpoint ensures that the cell is large enough to divide, and that enough nutrients are available to support the resulting daughter cells. Cell Division - Notes Gallery

  7. Station 2 – S(Synthesis) Description: Synthesis of DNA molecules takes place as chromosomes are replicated. Key proteins are also synthesized. Cell Division - Notes Gallery

  8. Station 2 – S(Synthesis) DNA replication: Use the color code key to color the replicating DNA strand in your resource book. Nitrogenous Bases Color Key Adenine Thymine Guanine Cytosine Nitrogenous Bases Color Key Adenine Thymine Guanine Cytosine Nitrogenous Bases Color Key Adenine Thymine Guanine Cytosine Nitrogenous Bases Color Key Adenine Thymine Guanine Cytosine Nitrogenous Bases Color Key Adenine Thymine Guanine Cytosine Nitrogenous Bases Color Key Adenine Thymine Guanine Cytosine Nitrogenous Bases Color Key Adenine Thymine Guanine Cytosine Nitrogenous Bases Color Key Adenine Thymine Guanine Cytosine Nitrogenous Bases Color Key Adenine Thymine Guanine Cytosine Cell Division - Notes Gallery

  9. Station 2 – G2 (Gap 2) Description: Many organelles and molecules required for cell division are produced here. Once this phase is complete, the cell is ready for mitosis. The G2 checkpoint ensures that DNA replication in S phase has been completed successfully. Cell Division - Notes Gallery

  10. Station 3 – Prophase Description: • The chromatin condenses into chromosomes. • The centrioles (in animals) separate, and a spindle begins to form. • The nuclear envelop breaks down. • Longest phase of mitosis. Cell Division - Notes Gallery

  11. Station 3 – Prophase Plant cell Cell Division - Notes Gallery

  12. Station 3 – Prophase Animal cell Cell Division - Notes Gallery

  13. Station 4 – Metaphase Description: • The chromosomes line up across the center of the cell. • Each chromosome is connected to a spindle fiber at its centromere. Metaphase checkpoint ensures that all of the chromosomes are attached to the mitotic spindle by a kinetochore . Cell Division - Notes Gallery

  14. Station 4 – Metaphase Plant cell Cell Division - Notes Gallery

  15. Station 4 – Metaphase Animal cell Cell Division - Notes Gallery

  16. Station 5 – Anaphase Description: • The sister chromatids separate into individual chromosomes and are moved apart. • A cell plate forms in plant cells. Cell Division - Notes Gallery

  17. Station 5 – Anaphase Plant cell Cell Division - Notes Gallery

  18. Station 5 – Anaphase Animal cell Cell Division - Notes Gallery

  19. Station 6 – Telophase Description: • Nuclear envelope forms around each new set of chromosomes • Spindle breaks down • Chromosomes uncoil • A cell wall begins to form in plant cells. Cell Division - Notes Gallery

  20. Station 6 – Telophase Plant cell Cell Division - Notes Gallery

  21. Station 6 – Telophase Animal cell Cell Division - Notes Gallery

  22. Station 7 – Cytokinesis Description: • Cytoplasm pinches in half. • Daughter cells have an identical set of duplicate chromosomes. Cell Division - Notes Gallery

  23. Station 7 – Cytokinesis Plant cell Cell Division - Notes Gallery

  24. Station 7 – Cytokinesis Animal cell Cell Division - Notes Gallery

  25. Station 8 – Phase Identification Look at the onion root tip cells in your booklet and see how many cells you can find in each stage. Chose a color for each stage and outline the cell in that color. Cell Division Color Key Interphase Prophase Metaphase Anaphase Telophase Cytokinesis Cell Division - Notes Gallery

  26. Station 9 – G0 (G zero) • If the cell does not receive a signal to “go ahead” at the G1 checkpoint it will not go into the dividing phases (Mitosis) • The cell is now said to be in G0 • Most cells in your body are in this stage. Cell Division - Notes Gallery

  27. Station 9 – G0 (G zero) • Examples of cells in G0 • Nerve cells • muscle cells • Liver cells (although these cells can be “called back” into the dividing phases of mitosis based on external cues such as growth factors) Cell Division - Notes Gallery

  28. Station 10 – Cancer • Cancer is a disorder in which some of the body’s own cells lose the ability to control growth. • Cancer cells do not respond to the signals that regulate the growth of most cells (G1 checkpoint is bypassed). • As a result, they divide uncontrollably and form masses of cells called tumors that can damage the surrounding tissues.

  29. C A N C E R Station 10 – Cancer Cause/Effect What causes the loss of growth control that causes cancer?? Take a Cause/Effect map. Color code it correctly. Fill in the various causes of cancer. Fill in the effects for each cause. Cell Division - Notes Gallery
