Specialised Cells & Differentiation

• What are the two important concepts covered in the video?

  Specialized cells and differentiation
• What are specialized cells?


  Cells that have specific roles in the body
• How many types of specialized cells are there approximately in humans?


  Around 200 types
• Name two examples of specialized cells in animals.


  Sperm cells and muscle cells
• Name two examples of specialized cells in plants.


  Root hair cells and xylem cells
• What is the role of a sperm cell?


  To deliver genetic material to an egg cell for fertilization
• Why does a sperm cell have half as much genetic material as a normal adult cell?


  To combine with the egg's genetic material to form a normal cell's worth
• What adaptation helps a sperm cell swim to the egg?


  The flagellum, which acts like a tail
• How does the streamlined shape of a sperm cell assist its function?


  It helps the sperm cell swim efficiently
• What is the function of mitochondria in sperm cells?


  To provide energy for swimming
• What do sperm cells have at their front to aid in fertilization?


  Digestive enzymes to break into the egg cell
• What are the general characteristics of specialized cells?


  • Specific role in the body
  • Unique shape and structure
