- 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.
