Specialised cells & Differentiation

• Specialised cell

  Cell that is adapted to perform a particular function
• What does differentiation mean

  Process by which cells b come specialised
• Why is differentiation important

  Allows the production of different types of cells, which can them form viral parts of the body
• Sperm cells role

  To deliver genetic material to an egg cell, and fertilise it
• Sperm cell adaptations

  Half as much genetic material so when it forms with an egg it will have the normal amount

  Lots of mitochondria for movement

  Has a flagellum so it can swim to reach the egg

  Streamlined to make swimming easier

  Has digestive enzymes in its her so it can break through the wall of the egg
• Root hair cell

  Has large surface area to absorb water and mineral ions

  Has lots of mitochondria to provide energy for active transport

  Has lots of protein channels to transport water and mineral ions into cell
