It is a plant which is able to survive in an environment with little available water or moisture
(plants adapted to dry habitats).
They are adapted to conditions of low water availability.
An example of a xerophytes plant is a Cactus.
They have very few stomata and a thick waxy cuticle.
Marrum grass has the same characteristics.
There are hairs on the plants, the stomata are in pits and the leaf is curled round. These
features reduce the rate of diffusion. They increase the concentration of water vapour on the
outside of the stomata. This reduces the concentration gradient.
They live in deserts where low rainfall amounts are the norm, but xerophytes such as
the bromeliads can also be found in moist habitats such as tropical forests,
Adaptations of xerophytes include reduced stomata and cuticle to maintain optimal amounts
of water in the tissues by reducing transpiration. The typical morphological consequences of
these adaptations are collectively called xeromorphisms.
Xerophytes plants have very different stomata to normal plants. They have less stomata of their
leaves than normal plants do. They also have a variety of different stomata and features. These
Stomata open at night
All of these and more contribute to reduce the amount of water lost through the plant.
