mitosis

• Interphase


  -80% of the cell life is in this stage

  -this isnt apart of mitosis

  -organelles & DNA replicate

  -chromosomes get ready to divide
• Prophase (2)


  -nuclear membrane begins to break

  -chromosomes condense become thick visible and short

  -spindle fibres start to appear
• Metaphase(3)


  -chromosomes go to the centre of the cell

  -nuclear membrane breaks completely
• Anaphase(4)


  -chromosomes duplicate (2) and the cell

  • they go on the opposite sides of the cell
• Telophase(5)


  -nuclear membrane begins to form

  -daughter cells begin to form

  -chromosomes become smaller and thinner
• Cytokinesis


  -daughter cells are formed and are the genetically identical to the parent cell
• Uses of mitosis


  -growth and repair

  -asexual reproduction
• Mitosis


  a cell dividing into 2 genetically identical diploid cells
• 23rd chromosome is


  the sex cell
• meiosis 


  cell division to form gametes, cells divide into 4 haploid daughter cells, have 2 divisions
• meiosis uses


  for sexual reproduction
• asexual reproduction


  when you only need one cell to divide into(form) more cells
• gametes


  sex cells
• haploid


  unpaired chromosomes (23 individual)
• diploid


  paired chromosomes(46 individual, 23 paired)
• where does mitosis occur


  in somatic cells (any body cells)
• where does meiosis occur


  in the testes or ovaries
