Microteaching-mitosis

  1. 2. MITOSIS <ul><li>At the end of this lesson, students are able to: </li></ul><ul><li>Understanding mitosis </li></ul><ul><li>Draw and label the phases of mitosis </li></ul><ul><li>Identify the changes occur in each phase </li></ul><ul><li>State the functions of mitosis in cell organism </li></ul>
  2. 3. MITOSIS Prophase Metaphase Anaphase Telophase 4 stages Is the process in which a parent cell divide and produce two daughter cells that are genetically to the parent cell.
  3. 4. ANIMAL CELL
  4. 5. <ul><li>Chromosomes in the nucleus condense and become more tightly coiled. </li></ul><ul><li>The sister chromatids which are held together at centromere become visible. </li></ul><ul><li>At the cytolaplasm, spindle fiber begin to form and extend between the centrioles. </li></ul><ul><li>End of this phase, the nucleolus disappear and the nuclear membrane disintegrates. </li></ul>1 PROPHASE
  5. 6. <ul><li>Centromere of all chromosomes are lined up on the metaphase plate. </li></ul><ul><li>The two sister chromatids are still attached to one another at the centromere. </li></ul><ul><li>Metaphase end when the centromeres divide </li></ul>2 METAPHASE
  6. 7. <ul><li>Centromere divides into two. </li></ul><ul><li>Chromatid sisters separated and move towards the opposite poles of the cell. </li></ul><ul><li>End of this stage, chromosomes reach the poles. </li></ul>3 ANAPHASE
  7. 8. <ul><li>Chromosomes begin uncoil. </li></ul><ul><li>The formation of nuclear membrane. </li></ul><ul><li>The chromosomes become less visible under the microscope. </li></ul><ul><li>The spindle fibers disappear and a new nuclear membrane form around each set of chromosomes. </li></ul><ul><li>The two daughter nuclei formed. </li></ul><ul><li>Hence, completed the process of mitosis </li></ul>4 TELOPHASE
  8. 9. CYTOKINESIS <ul><li>Is the division of cytolplasm. </li></ul>CYTOKINESIS Animal cell Begins when the cell membrane contracts due to the interaction of myosin and actin microfilaments at the cell membrane forming cleavage furrow. Furrow cleavage continues until two daughter cells are completely separated. Plant cell Vesicle fprming a cell plate. The cell fuses to form new cell walls and plasma membanes. Two daughter cells are formed at the end of cytokinesis.
  9. 10. IMPORTANCE OF MITOSIS Reproduction Growth Mantaining Repairing <ul><li>Increase no. of cell, </li></ul><ul><li>Contribute the growth of tissue and organs of multicellular organism </li></ul><ul><li>Some of the organism reproduce asexually by mitosis. </li></ul><ul><li>Ex: paramecium, euglena and plants </li></ul><ul><li>Repair worn out and damaged tissue </li></ul><ul><li>Maintain the same no. of chromosomes as the parent cell and genetically similar to the parent cell </li></ul>
  10. 11. CONCLUSION <ul><li>Mitosis is the process of dividing cell from a parent cell form two daughter cells, identically as parent cell </li></ul><ul><li>There is stages in mitosis process </li></ul><ul><li>Prophase </li></ul><ul><li>Metaphase </li></ul><ul><li>Anaphase </li></ul><ul><li>Telophase </li></ul><ul><li>The process completed the separation of cytoplasm is cytokinesis. </li></ul><ul><li>Importance of mitosis are in growth, reproduction, repairing and mantaining the number of chromosome in daughter cell as parental. </li></ul>
