cell division

• what are the stages of the cell cycle?

  interphase:-growth phase 1 = growth of cells and synthesis of organelles-synthesis phase = replication of dna-growth phase 2 = cell checks dna and any makes any repairs. cell organelles grow and divide. energy stores increased. cell prepares for division

  nuclear division (mitosis)

  cytoplasmic division
• what are the 4 stages of mitosis?

  prophasemetaphaseanaphasetelophase
• what is prophase?


  chromatin condenses into chromosomes and the nucleolus disappears.
• what is metaphase?


  the chromosones line up along the metaphase plate (equator). the spindle fibres released from the poles now attatch to the centromere and chromatid
• what is anaphase?


  the centomeres divide in 2 and individual chromatids are pulled to opposite poles of the cell. they are now referred to as chromosomes
• what is telophase?


  chromosones at each pole begin to become longer and thinner and eventually disintergrate forming nucleus.the cytoplasm then splits and 2 genetically identical cells are produced.
