Cell cycle

  1. 1. Cell Cycle<br />
  2. 2. Interphase-Growth and Perpetration.<br />During this first stage, the cell grows in size while it creates proteins and nutrients essential for survival.<br />
  3. 3.
  4. 4. Interphase-Replication<br />During this stage, the cell has two sets of DNA<br />
  5. 5.
  6. 6. Interphase – continued growth and preperation<br />In this stage, the cell continues to grow and make proteins for the daughter cells.<br />

  10. 10. Mitosis-early Prophase <br />During early prophase, the chromosomes that were created in the ‘replication’ stage coil up into the X shape, and become visible under a microscope. The nucleolus disappears, and only the membrane remains. Spindle fibres, tiny tube-like structures, begin to appear as well as centrioles, organelles that organize the fibres.<br />

  16. 16. Mitosis- late prophase<br />In late Prophase, the spindle fibres finish forming and attach their centromeres to the chromosomes. The nuclear membrane disappears. <br />
  17. 17.
  18. 18. Mitoses - Metaphase<br />In Metaphase, the spindle pull the chromosomes in to the center of the cell.<br />
  19. 19.
  20. 20.
  21. 21. Mitosis - Anaphase<br />In Anaphase, the spindle fibres shorten and pull the chromosomes apart, allowing the sister chromatids to move to opposite poles. <br />

  30. 30. Mitosis - Telophase<br />In Telophase, the final stage of Mitosis, a complete set of chromosomes have now moved to opposite ends of the two ‘daughter’ cells. The spindle fibres start to disappear while a nuclear membrane forms around the chromosomes. A nucleolus also forms in each newly formed nucleus, meaning the cell is ready to divide.<br />
  31. 31.
  32. 32. Cytokinesis<br />The final stage of the cell cycle, Cytokinesis, is when the cell finally divides. The nuclei separate into two daughter cells. The new cells are identical to the parent cells. In animals, the membrane pinches together to form these daughter cells, while in plants a plate forms to divide them.<br />Animal<br />Plant<br />
