TRANSCRIPT

  • TABLE COMPARING MITOSIS AND MEIOSIS

    MITOSIS MEIOSISNumber of divisions One Two

    Number of cells produced 2 4 (tetrad)

    Chromosome sets (=n) 1n ! 1n; 2n ! 2n 2n ! 1n

    Purpose Vegetative growth Sexual reproduction;produce spores to startgametophyte generation,or produce sex cells(gametes) directly (mostanimals)

    Site In plants, apical and rootmeristems and vascularcambium

    In plant, microsporangiaand megasporangia

    Cell Division PhaseProphase I Chromosomes duplicate

    (chromatids);chromosomes do not pair

    Chromosomes duplicate(chromatids); likechromosomes pair

    Metaphase I Chromosomes (pairedchromatids) line up atequatorial plate

    Paired Chromosomes (4chromatids) line up atequatorial plate

    Anaphase I Chromatids separate Chromosomes pairsseparate; chromatids staytogether

    Telophase I 2 identical cells formedVoil youre done!

    2 nucleii or cells formed;each with one set ofchromosomes as pairedchromatids

    Prophase II Chromosomes, as pairedchromatids condensed,distinct

    Metaphase II Paired chromatids atequatorial plate

    Anaphase II Separation of chromatids

    Telophase II Formation of 4 nucleii orcells; each haploid (1n)
