Presentation Transcript

  1. O: You will be able to explain Mitosis. Do Now: Explain how you think cells make more cells.

  2. Mitosis • Mitosis is the process of cell division where one parent cell divides in half to produce 2 identical daughter cells. • Mitosis is known as the cell cycle. • The cells winds up being two cells that are exactly the same as the first one. • Why could this be a problem?

  3. How can it split? • Cells contain chromosomes. • Chromosomes are structures located in the nucleus containing DNA. • The amount of chromosomes determines what the organism is. • A human has 46 chromosomes.

  4. There are five stages of Mitosis • Interphase • Prophase • Metaphase • Anophase • Telophase

  5. Interphase • Interphase is the longest phase of the cell cycle. • During it the cells grows and performs its normal job. This is most of the cell’s life. • The nucleus breaks down into chromosomes. • At the end of Interphase the chromosomes duplicate.

  6. Prophase • During Prophase the chromosomes pair up with their “twin” • The centrioles move to opposite ends of the cell.

  7. Metaphase • During Metaphase chromosome line up in the middle of the cell. • The centrioles send spindle fibers that attach to the chromosomes.

  8. Homework • There are two steps left. What do you think happens in the next two steps? • If a human has 46 chromosomes, where do you think they got them from? • Why does interphase take up over 95% of a cell’s cycle?

  9. Anaphase • Spindle fibers pull apart the chromosomes and the chromotids move to opposite ends of the cell.

  10. Telophase • The cell membrane or cell wall for a plant, starts to pinch together to create 2 new cells. • The nucleus begins to reform.
