Animal Cell Specialisation

• 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.
