Mangroves in Australia Essay -- Plants Botany Essays

Mangroves in Australia The mangrove communities of Australia are slightly of the close extremely adaptive plant communities in the world. These plants lodge in an environment that is a lot engulfed with seawater. This environment is considered an arid environment due to the lack of fresh water. The plants of the mangrove community must develop several adaptations to deal with the environment. The environment these plants very much inhabit is referred to as an intertidal zone. The intertidal zone is the transition surrounded by the table salty ocean to the fresh water of the interior of the continent or island. To deal with the salty environment, mangrove plants have developed change roots. In some species, the roots filter the incoming seawater. These modified roots too help to support the tree in the muddy substrate. The roots are considered a xeromorphic feature, a display feature that tends to conserve or defend water. These roots to a fault provide oxygen i ntake by structures strain pneumatophores. This ability is important in times of low soil aeration. The leaves are covered with a waxy cuticle that helps retain water. In some species, the leaves are responsible for salt secretion, while others store excess salt in leaves until they fall off the tree. The mangrove species also have modified reproductive structures. Most cums develop while still attached to the refer tree. This enhances their chance of survival. These seeds are also buoyant, which allows them to float to a less risible spot, away from the parent tree and start growing. Some species seeds shed their seed coat at particular water temperature and water salinity. Mangrove species discover different types of pollen for different plants. These different types of pollen ... ...e land (Maguire 2000). Mangroves are endangered by human development. Conservation and management techniques need to become an important let go to preserve these unique and highly advance communities.SummarThe mangroves are some of the most highly evolved plant communities in the world. These plants have overcome the harsh conditions from which they live in. One of the most obvious adaptations is the modified root structures that not lonesome(prenominal) help support the plant in the muddy substrate, but may aid in oxygen intake in some species. another(prenominal) notable adaptation that mangrove plants exhibit is their modified reproductive structures called propagules. These seeds rattling begin development while still attached to the parent tree. Mangroves also provide important services such as filtering out toxins in outgoing streams that would normally damage coral reefs.
