Plant Adaptations A wetland is a harsh environment physiologically. Aquatic plants can't deal with periodic drying and temperatures tend to be more extreme because the water's shallow terrestrial plants can't deal with long floods. Stresses include anoxia and wide salinity and water fluctuations.
There are many kinds of aquatic plants, each with distinct adaptive characteristics; these plants may be either entirely floating, submerged or partially submerged, as in the case of many swamp and wetland plant species. Water Lily The water lily is an example of a floating plant. Floating plants grow on the surface of the water and are anchored by their roots to bottom of the body of water.
Water lilies have adapted so that chloroplasts are present only on the surface of the leaves that are exposed to the sun. Chloroplasts contain the pigments that absorb sunlight for photosynthesis, a reaction that plants need to create energy.
As the other side of the leaf is permanently submerged, no chloroplasts are needed. Another important adaptation of water lilies is the lateral spreading of their leaf canopy. Water lilies depend upon the surface tension of the water to anchor their leaves, making them prominent in freshwater pond and lake situations, where water is typically still and calm.
Hornwort The hornwort is a type of aquatic plant that remains completely submerged in the water. Submerged plants may or may not have a root system, as the role of the root system is reduced merely to that of an anchor in the underwater soil.
Hornworts do have roots, but they have adapted to spread nutrients throughout the plant body without them. In addition, structures such as the xylem and phloem, which are responsible for water retention, nutrient distribution and structural support are absent in hornworts, for all of this is achieved by the suspension and movement of water and nutrients throughout their aquatic environment.
While most plants require heavy structural material for growth and strength, the body of the hornwort is minimal in this regard, for its light and limp composition provides less resistance to the surrounding water, and thus more resistance to possible damage.
Sciencing Video Vault Cattail The cattail is an example of a partially submerged plant.
They may be found in swamps, bogs and wetlands with either permanent or seasonal submergence in water. Cattails have waxy leaves that protect them from the water, as well as chloroplasts on both sides to take advantage of the sun when they are emerged.
They also tend to be tall, in order to guarantee some portion of emergence for sunlight absorption. Cattails have adapted very efficiently with regards to reproduction.Aquatic plants require special adaptations for living submerged in water, or at the water's surface.
The most common adaptation is aerenchyma, but floating leaves and finely dissected leaves are also common. Aquatic plants can only grow in water or in soil that is permanently saturated with water. They are therefore a common component of wetlands. Plants must adapt to salt water or fresh water (or even both), living in water, sand, dirt, having little sunlight, being in a moist area, and having many insects and animals around to survive in the Mangroves Swamps.
Interestingly, wetland plants in saltwater have the same problem plants in arid climates havedifficulty in getting and keeping water. Because of the salt levels, water tends to leave the plant via osmosis, or at least not enter the plant. Animal Adaptations. Because animals are more complex than plants, their adaptations are more varied. They exhibit biochemical responses at the cellular level, physiological response of the whole organism such as modification of the circulatory system, or a behavioral response such as modified feeding habits. The plants look worse the greater the salinity of the water, except for the healthy plant in the % water. Why do you think that plant remains healthy even though it is in salty water? It must have something helping it maintain that the other three plants do not.
Animal Adaptations Many plants and animals have adapted to the freshwater biome and could not survive in water having a higher salt concentration. As this ecosystem covers a vast portion of the world, the animal life found can vary considerably.
Aquatic plants have adapted in a number of special ways in order to cope with their environments. There are many kinds of aquatic plants, each with distinct adaptive characteristics; these plants may be either entirely floating, submerged or partially submerged, as in the case of many swamp and wetland plant .
Mangrove swamps are coastal wetlands found in tropical and subtropical regions. They are characterized by halophytic (salt loving) trees, shrubs and other plants growing in brackish to saline tidal waters. These wetlands are often found in estuaries, where fresh water meets salt water and are.
