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 fertilization?

  • 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 contain genetic information?

  They contain genetic information in the nucleus
• What is the role of mitochondria in sperm cells?

  • Provide energy needed for swimming
• What is the function of enzymes in sperm cells?

  To digest their way through the outer layer of the ovum
• What is the primary function of nerve cells?

  To send electrical impulses around the body
• What adaptations do nerve cells have for transmitting 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 role of myelin in nerve cells?

  To insulate the axon and speed up transmission
• How do dendrites contribute to the function of nerve cells?

  They increase the surface area for connections with other nerve cells
• What is the primary function of muscle cells?

  To contract and get shorter
• What adaptations do muscle cells have for contraction?

  • Contain protein fibers that change length
  • Packed with mitochondria for energy
• How do muscle cells work together?

  They form muscle tissue
• What is a key feature of muscle cells?

  • They can contract (get shorter)
• What will be covered in more detail in a later topic regarding muscle cells?

  Their role in forming muscle tissue
• Where can students find more questions on specialized animal cells?

  In the vision workbook
• What should students be able to do by the end of the video?

  Describe how sperm cells, nerve cells, and muscle cells are specialized
