Mitosis

• What happens before cell divides?

  Nuclear membrane dissolves so it has more room
• What happens to the nuclear membrane?

  Dissolves and then forms around the identical sets of chromozones.
• cells must divide in order to replace worn-out cells and to grow and repair tissues.

  
• What happens to the chromosomes?

  1. They Become smaller and fatter
  2. Then they gather in the middle
  3. Split forming daughter cells
• Process of Mitosis


  step By step

  
• How does the use of mitosis different in mature animals?

  In adults, they only need to repair. They don’t need to grow. However, a child still needs to grow.
• Explain why the cells genetic material has to be Copied before it divides by mitosis?

  It needs to replicate, so it can be identical and have the same number of chromosomes in each cell.
