- - - - myelin sheath
        
        stops electrical impulse moving through body
    - - no nucleus
        
        more space for oxygen
      - biconcave
        
        more surface area
    - - lots of mitochondria
        
        produce lots of energy
    - - lots of mitochondria
        
        for energy to move to egg
      - flagella
        
        to move to egg
      - has digestive enzymes
        
        to break into egg
  - - - in animals
      - can be anywhere in body
      - embryonic stem cells can be anything
- - - - metaphase
        
        anaphase
        
        telophase
        
        cytokinesis

        two identical daughter cells are formed
        
        nuclear envelopes form around the two new nuclei
        
        spindle fibres pull chromosomes apart, centrosome first to each side of the cell
        
        chromosomes line up in centre of cell
      - DNA supercoils and condenses, becomes shorter and fatter
      - nuclear envelope disappears
    - - all DNA is replicated
- - - - meiosis II
        
        prophase II
        
        metaphase II
        
        anaphase II
        
        telophase II
        
        cytokinesis
      - prophase I
        
        metaphase I
        
        anaphase I
        
        telophase I
