Year 10, Pathway C 2012

 DNA Replicates in preparation for cell division  Each new cell needs the same DNA

 Mitosis is the reproduction of cells for growth and repair  Meiosis is the production of gametes (sex cells with half the number of chromosomes)

MitosisMeiosis For growth and repairFor producing gametes One stage of divisionTwo stages of division Produces two daughter cellsProduces four daughter cells Daughter cells have same number of chromosomes as parent (diploid) Daughter cells have half the number of chromosomes of parent (haploid) Daughter cells have pairs of chromosomes Daughter cells do not have pairs of chromosomes (only one of each pair)
