MITOSIS MITOSIS Presentation Transcript

  • Mitosis By Shawn
  • Definition
    • Mitosis= cell division in which the nucleus divides into nuclei containing the same number of chromosomes of sprit chromosomes .
  • Mitosis
    • It is called prophase
    • The chromatin begins to form it self in to the defiant shapes.
    • The nucleus begins to be absorbed in to the middle.
    • The nucleolus begins to disappear .
  • Nucleus
    • The nucleus surrounds the cell and gets absorbed in to the cell when it is in prophase .
    • The nucleus helps protect the cell form getting damage .
  • Nucleus
    • The nucleus also has another job and that is to let in things that are needed like ATP.
    • The nucleus also has to protect form invaders like colds and other viruses
  • Chromosomes
    • A chromosome is an organized structure of DNA and protein that is found in cells. A chromosome is a singular piece of DNA.
  • Chromosomes
    • Chromosomes have four DNA strips when taken a part
    • When prophase occurs the spindle fibers will pull the chromosomes a part equally .
  • Cell membrane
    • The cell membrane consists primarily of a thin layer of amphipathic phospholipids
  • Other facts
    • Spindle fibers are used to separate the chromosomes equally on each side of th cell.
  • Cancer
    • Cancer has to do with the reproduction of the same cell and if there is a problem with one cell the body will destroy it.
    • If there is two many the body cant keep up with the reproduction of the bad cells so that causes a tumor a can lead to cancer
  • The End
