cell cycle / mitosis

• The cell cycle

  there are 3 main stages in the cell cycle

  • 1 interphase the stage where the cell
  • grows
  • spends most of its life
  • increases the number of structures such as ribosome and mitochondria
  • replicates its DNA to form two copies of each chromosome
  • .
  • 2. miTOsis the stage where
  • one set of chromosome is pulled to each end of the cell
  • the nucleus divides
  • .
  • cell division the stage immediately after mitosis where
  • cell membranes and cytoplasm divide
  • two identical cells form
• The cell that divides is called the parent cell

  The parent cell forms 2 daughter cells
• The parent cell is a diploid cell this means it has 2 sets of chromosomes Before the parent cell divides each chromosome is copied exactly . When the cell divides in two each cell gets a copy of each chromosome The daughter cells are genetically identical to each other and the parent cells they are also diploid cells
• mitosis produces new body cells for:

  • growth
  • repair damaged parts of the body
