  • Specialised Cells
    • Palisade Leaf Cells
      • chloroplasts
        • photosynthesis
      • tall shape
        • large surface area
        • absorbs C02
      • thin
    • Guard Cells
      • opens and closes stomata
      • fill with lots of water- tiurgid
      • short of water- flaccid
      • thin outer walls
