animal cell specialisation

• What are the three specialized animal cells discussed in the video?

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

  Differentiation
• What adaptations do sperm cells have for 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 do sperm cells store genetic information?

  In the nucleus
• What are the key features of nerve cells?

  • Long axon for transmitting impulses
  • Myelin sheath for insulation
  • Synapses for passing impulses to other cells
  • Dendrites to increase surface area for connections
• What is the main function of nerve cells?

  To send electrical impulses around the body
• What role does myelin play in nerve cells?

  It insulates the axon and speeds up impulse transmission
• What adaptations do muscle cells have for their function?

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

  They can contract
• How do protein fibers in muscle cells contribute to their function?

  They shorten when the muscle contracts
• What do muscle cells require for contraction?

  Energy from mitochondria
• How do muscle cells work together?

  • They form muscle tissue
  • Collaborate to produce movement
  • Each cell contributes to the overall contraction
• What is the significance of the genetic information combining during fertilization?

  It creates a new organism with genetic material from both parents
• How do the adaptations of sperm cells, nerve cells, and muscle cells reflect their functions?

  Each cell type has specific structures that enhance its ability to perform its unique role
