Cell specialisation

• how are red blood cells specialised

  dimple to carry more oxygen, no nucleus to allow more space for haemoglobin
• Sperm cell 


  Flagella for swimming through the uterus, extra mitochondria for more energy, head is pointed and is covered in an enzyme that helps break into the egg
• Root hair cell


  elongated to increase surface area to absorb water and nutrients from the soil
• nerve cell


  Large surface area, covered in Milon to stop electricity going anywhere else, the axon allows for electrical impulses
• Muscle cell


  Lots of mitochondria, able to contract quickly, long to give them space to contract
• Phloem


  Sieve cells, sieve cells allow some stuff to go through, carries water and food, goes two ways
• Xylem 


  Thick walls, doesn’t have walls between cells, carries minerals and water, one way
