  • Specialised Cells
    • Cells have adaptations to help them carry out a function
      • E.g. cells with lots of mitochondria must need lots of energy
      • E.g. cells with lots of ribosomes must make a lot of protein
    • Cone cells in the eye
      • Light sensitive
      • Connect with optic nerve to allow sight
    • Mesophyll cells in leaves
      • Trap a lot of light to increase photosynthesis
    • Root hair cells in plants
      • Increase the surface area of the root
        • Water and minerals absorbed more easily
      • Close to xylem tissue
        • Transport water/mineral ions through plant
