Animal cell Specialisation

• What is the process called when cells become specialized?

  Differentiation
• What are the adaptations of sperm cells that enable them to carry out their function?

  • Long tail for swimming
  • Streamlined shape
  • Packed with mitochondria for energy
  • Contains enzymes to digest the ovum's outer layer
• What is the primary function of sperm cells?

  To join with an ovum during fertilization
• How are nerve cells adapted to send electrical impulses?

  • Long axon for impulse transmission
  • Myelin sheath for insulation and speed
  • Synapses for passing impulses to other nerve cells
  • Dendrites to increase surface area for connections
• What is the main role of nerve cells?

  To send electrical impulses around the body
• What adaptations do muscle cells have for contraction?

  • Contain protein fibers that change length
  • Packed with mitochondria for energy
  • Work together to form muscle tissue
• What is the key feature of muscle cells?

  They can contract (get shorter)
• Why do sperm cells contain a high number of mitochondria?

  To provide energy for swimming
• How does the structure of nerve cells facilitate their function?

  It allows for rapid transmission of electrical impulses
• What role do enzymes play in sperm cells?

  They allow sperm to digest the ovum's outer layer
• How do muscle cells work together?

  They work together to form muscle tissue
