- The Amazing and Mystical Properties of Marram Grass (the most magical of all plants)
- Anatomical Adaptations
- Long roots to reach water underground
- Leaves are curled to reduce surface area
- Lower epidermis covered in hair to reduce air movement
- Fewer stomata so less water vapour lost
- Leaf covered in a thick waxy cuticle to reduce evaporation of water from the cells
- Physiological/Biochemical Adaptations
- Leaves contain many lignified cells that provide support when water is not available to keep cells turgid
- Rolls its leaves due to the action of hinge cells in the lower epidermis which lose water and become flacid, rolling the leaf
- The guard cells open and close the stomata, open when water is available, closed when water is not
- Marram is not very salt tolerant but maintains cell water potential that is lower than other plants, enabling it to survive near the sea
- Behavioural Adaptations
- When covered by sand marram will grow more quickly to reach the sunlight
- The leaves roll and the stomata close as a reaction to a lack of water
- Anatomical Adaptations
