1. 1 1 Cell Cycle

2. Skin cancer - the abnormal growth of skin cells - most often develops on skin exposed to the sun. Cell that reproduce by asexual reproduction reproduce constantly.

3. Animated Cell Cycle http://www.cellsalive.com/mitosis.htm Interphase Prophase Metaphase Anaphase Telophase & Cytokinesis

4.  Longest part of cell life  Cell carries out normal activities  DNA in long strands called chromatin  Centrioles as a pair Centrioles

5. Chromatin doubles to form chromosomes (# doubles) Other cell parts also double Editing of DNA to repair errors CELL MEMBRANE Nucleus Cytoplasm Late Interphase Centrioles

7. Chromosomes coil and become visible Centrioles (or poles) appear and begin to move to opposite end of the cell. Spindle fibers form between the poles. Nuclear membrane disappears. Centrioles Sister chromatids Spindle fibers Stage II- Mitosis Phase # 1- Prophase

8. Animal Cell Plant Cell Photographs from: http://www.bioweb.uncc.edu/biol1110/Stages.htm Spindle fibers Centrioles

9. Chromosomes line up in the middle of the cell on the spindle fibers. Centrioles Spindle fibers Phase # 2- Metaphase

11. Chromatids (or halves of chromosomes) separate and begin to move to opposite ends of the cell. Centrioles Spindle fibers Phase # 3- Anaphase

13. Chromatids finish separating. Nuclear membrane reforms Chromatids unwind and become chromatin. Nuclei Chromatin Phase # 4 - Telophase

15. Cytoplasm and cell organelles divide evenly Two new cells are formed STAGE III - Cytokinesis
