    • Cell Differentiation
      • Most cells in growing organisms differentiate into cells that are specialised for a particular function.
      • animals
        • most cells differentiate at an early stage
          • in mature animals, cell division is mainly for repair and replacement of cells
      • plants
        • many cells are able to divide and differentiate into specialised cells throughout life
    • Cells that remain able to divide to form different specialised cells are called STEM CELLS
      • bone marrow
      • early embryo
        • Stem Cells
          • bone marrow
          • specialised cells (e.g. nerve cells)
            • in the future may be used to treat conditions such as PARALYSIS
