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
