  • Marram Grass
    • Rolled Leaves
      • Large thin walled epidermal cells, called hinge cells, at the base of the groove become plasmolysed as a result of excessive water loss through transpiration.
      • This causes the leaves to roll, with the upper surface facing inwards.
        • This reduces the leaf area exposed to the air and so reduces the transpiration rate.
    • Hairs
      • The inner layer has hairs to trap water vapour. This decreases the water potential gradient between inside and outside the leaf, reducing the rate of transpiration.
    • Thick cuticle
      • The outer layer has a thick waxy covering that is waterproof and reduces water loss.

why are there no stomata on the outer surface?
