What are xerophytes?

One of the largest miracles in the world of plants involves the unique adaptability of xerophytes. These interesting plants have the ability to change both their physical structure and behavior to survive and grow under extreme conditions such as drought. Xerophytic plants have an extraordinary way of storage and maintaining water. These succulent leaves and stems hold and store moisture. Less leaves also reduce the amount of transpiration or loss of water. Many of these plants have also adapted to replacing traditional leaves with spine or thorns. Examples of this adaptation include caches and succulent plants that usually occur in dry desert areas where water is rare. This also helps them withstand the more temperatures that often accompany the desert climate. Xerophytes usually close pores that are called stomata during the day, allowing them to avoid large loss of water. Instead they open them at night; And although some water loss may occur during night transpiration, it is very little.

Cacti and succulents slowly shrink when moisture is lost, survives on their stored water in leaves or stems. In addition, these xerophytes have extensive, yet shallow root systems that also store water. Aviation roots are another xerophytic feature. Many of these plants are found in tropical areas, unlike dry. Examples include bromeliads, orchids, Spanish moss and staghorn fern. These xerophytes are often found growing in the limbs of forest trees. Their suspended roots not only serve as anchors, but also absorb moisture from moist air.

Some xerophytes also live in Arctic areas. These plants often rely on many silver hair and succulent leaves for survival. The leaves store moisture, while light hairs reflect sunlight and serve as wind barriers. This adaptation allows them to survive in cold, dry and relatively hardBreaths. Other types of xerophytic plants survive by being sleeping during the dry season and then abating as the moisture returns. Bulbs are a good example of this adaptability.

cell plants are able to store water and nutrition for a long time, especially under conditions similar to drought. Other plants, such as lichens, some desert shrubs and even eyelashes, last for a longer time of drying. For example, the resurrection race may actually seem dead, but once the water is restored, it will revive quickly. Others, such as eferrals, can only live and reproduce during the wet season before death. They live long enough to leave the seed resistant to drought they hatch as soon as it rains.
