    Cards (23)

    • Specialized animal cells
      Cells that have adaptations which help them carry out a particular function
    • Differentiation
      When cells become specialized
    • Sperm cells
      • Long tail to swim to ovum
      • Packed with mitochondria to provide energy for swimming
      • Contain enzymes to digest outer layer of ovum
    • Fertilization
      The process where the genetic information of the ovum and sperm combine
    • Muscle cells
      • Contain protein fibers that can contract to shorten the cell
      • Packed with mitochondria to provide energy for contraction
    • Muscle cells work together to form muscle tissue
    • What are sperm cells specialised for?
      reproduction
    • What are nerve cells specialised for?
      rapid signalling
    • What are muscle cells specialised for?
      contraction
    • What are root hair cells specialised for?
      absorbing water and minerals
    • what are phloem and xylem cells specialised for?
      transporting substances
    • When does most differentiaiton occur?
      as an organism develops
    • What are undifferentiated cells called?
      stem cells
    • when do plant cells differintiate?
      dont ever lose this ability
    • In most animal cells the ability to differntiate is then lost at an early stage.
