  • Specialised Cells
    • As an organism develops, cells differentiate to form different types of cells. They become specialised
    • Most types of animal cells differentiate at an early age
    • Plant cells can differentiate throughout their whole life
    • As a cell differentiates:
      • It may change shape
      • Different sun-cellular structures develop to let it carry out a specific function
    • Specialised cells in animals
      • Sperm
        • Function
          • To fertile an egg cell
        • Adaptions
          • Long tails with muscle like proteins to swim towards egg
          • Full of mitochondria
          • A large nucleus containing genetic information to be passed on
          • Acrosome containing digestive enzymes to breaking down the outer layers of the egg cell
      • Nerve cells
        • Function
          • Carry electrical impulses around the body
        • Adaptions
          • Have lots of dendrites to connect to other nerve cells
          • Can get up to 25m long
          • Use chemicals to pass impulses to another cell
      • Muscle cells
        • Function
          • Proves the bones of a skeleton
        • Adaptions
          • Contains special proteins that can slide over each other making fibres contract
          • Contain many mitochondria to transfer energy needed for the chemical reactions to contract cells
