specialised cells and differentiation

• What are specialized cells?

  Cells that perform specific functions
• What is the process by which cells become specialized?

  Differentiation
• What types of organisms have specialized cells?

  Complex organisms like animals and plants
• Name two examples of specialized cells in animals.

  Sperm cells and muscle cells
• How many types of specialized cells are there approximately in humans?

  Around 200 types
• 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
• Why does a sperm cell have half the genetic material of a normal adult cell?

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

  A tail-like structure called a flagellum
• Why is the streamlined shape of a sperm cell important?

  It helps the sperm 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 fertilization?

  Digestive enzymes to penetrate the egg
• What is a key characteristic of specialized cells?

  They have specific shapes and structures
• How do red blood cells and nerve cells differ?

  They have different shapes and structures
• What is differentiation?

  The process by which cells become specialized
• What is a zygote?

  A fertilized egg cell
• What happens to the zygote during development?

  It divides by mitosis into multiple cells
• What occurs after the zygote divides into two cells?

  Those cells divide into four cells
• What is the significance of differentiation in development?

  It allows cells to perform specific roles
• What defines stem cells?

  Cells that can divide and differentiate
• What are the key points about specialized cells?

  • Specialized cells perform specific functions
  • They have unique shapes and structures
  • They contain different organelles based on their roles
• What is the process of differentiation and its significance?

  • Differentiation is how cells become specialized
  • It involves changes in shape, structure, and organelles
  • Essential for the development of complex organisms
