Animal Cell Specialisation

• What are the three specialized animal cells discussed?

  Sperm cells, nerve cells, muscle cells
• What is the process called when cells become specialized?

  Differentiation
• What adaptations do sperm cells have for fertilization?

  • Long tail for swimming
  • Streamlined shape
  • Packed with mitochondria for energy
  • Contains enzymes to digest ovum's outer layer
• How do sperm cells provide energy for swimming?

  Through mitochondria
• What are the key features of nerve cells?

  • Long axon for impulse transmission
  • Myelin sheath for insulation
  • Synapses for impulse transfer
  • Dendrites to increase surface area
• What are the key features of muscle cells?

  • Can contract to shorten
  • Contain protein fibers that change length
  • Packed with mitochondria for energy
  • Work together to form muscle tissue
• How do muscle cells work together?

  • Form muscle tissue
  • Contract in unison for movement
  • Provide strength and support
• What role do enzymes play in sperm cells?

  Help digest the ovum's outer layer
• What is a general characteristic of animal cells?

  They can look different based on function
• What is the significance of mitochondria in specialized cells?

  They provide energy for cell functions
