Differentiation and Specialised Cells

• 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 at the end 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 the digestive enzymes in sperm cells do?

  They break a hole into the egg cell upon reaching it
• What are the general characteristics of specialized cells?


  • Specific role in the body
  • Unique shape and structure
  • Different amounts of organelles
• What is differentiation?


  The process by which cells become specialized
• What is the starting point of human life?

  A single cell called a zygote
• What happens to the zygote after fertilization?


  It divides by mitosis into two cells, then four cells, and so on
• What occurs during the differentiation process?


  Cells change to become specialized with specific shapes and structures
• What are stem cells?


  Cells that can repeatedly divide by mitosis and differentiate into specialized cells
