Adaptations of XEROPHYTES
|
- adapted to dry conditions
- they have adaptations to conserve water by reducing transpiration - E.G Marram grass - thick cuticle on leaves - waterproofs leaf and prevents evaporation - sunken stomata in pits - hairs surrounding the stomata trap water vapour, maintaining humid air round the stomata and reducing water potential gradient. - Hinge cells, which cause the leaves to roll up, maintaining humid air around the stomata and reducing water potential gradient |
