Animal Cell Specialisation

• What does it mean for a cell to be specialized?

  It has adaptations for specific functions
• What is differentiation in cells?

  • Process where cells become specialized
  • Adaptations help carry out specific functions
• What is the primary function of sperm cells?

  To join with an ovum for fertilization
• What happens during fertilization involving sperm cells?

  Genetic information combines from sperm and ovum
• How do sperm cells adapt for swimming to the ovum?

  They have a long tail and streamlined shape
• What role do mitochondria play in sperm cells?

  They provide energy for movement
• What do sperm cells contain to digest the ovum's outer layer?

  Enzymes
• What is the primary function of nerve cells?

  To send electrical impulses around the body
• What is the structure of a nerve cell that carries impulses?

  A long axon
• How do synapses function in nerve cells?

  They allow impulses to pass between cells
• What do dendrites do in nerve cells?

  Increase surface area for connections
• What is the primary function of muscle cells?

  To contract and get shorter
• What allows muscle cells to contract?

  Protein fibers that change length
• What do mitochondria provide for muscle cells?

  Energy for muscle contraction
• How do muscle cells work together?

  • They form muscle tissue
  • Collaborate for coordinated movement
