how do plants in the wetland survive?

adaptations\nWetland plants are referred to as hydrophytic plants because they live in water.  These plants are herbaceous, shrubs, or trees that have developed a special adaptation that enable them to survive the stressful conditions characteristic of wetlands such as: \n\n                                                                       1.  fluctuations in water levels \n\n                                                                       2.  permanent saturation with water \n\n                                                                       3.  decreased oxygen \nhttp://web.utk.edu/~ctmelear/ossabaw/LeggettVestWilliams/N_Vest2.html\n\n1.  Many wetland plants have special air or pore spaces in their roots and stems called aerenchyma through which oxygen can enter the plant and be transported to its roots. \n\n2.  Some plants have hollowed stems that transport oxygen to the roots \n\n3.  Woody plants pump oxygen from their stems to their roots. \n\n4.  Many wetland trees have very shallow root systems, swollen trunks, or roots that grow above the ground.  Examples of this are the cypress knees seen in swamps. \n\n5.  Some plants develop adaptations that allow them to tolerate salt water.  These plants are called halophytes.  Some adaptations of these plants are: \n                    - develop ways to reduce salt intake by the roots called salt water exclusion \n                    - some take the salt in but have salt-secreting glands to remove the salt \n                    - Some develop salt concentrating glands like fleshy leaves.  They collect salt in these leaves and then shed them \n                    - Some plants have succulent leaves, store water, and then use it to dilute the concentration of salt \n                    - Some plants have salt water proofed theirselves by developing a waxy covering \n                    - Some reduce their leaf surface to minimize exposure to salt \n                    - some isolate salt into internal organs

There are all different types. In the south we have a lot of water plants and millions of pines on the North Shore. We have lots of swamps with cypress trees that grow in water that is several feet deep. There are marshlands with grass that grows in saltwater. If you look into the woods as you drive around the South of Louisiana, you'll see palmetto ferns. There are a lot of other ferns in Louisiana as well. On the oak trees, there is a special plant called a century fern. It looks dead until after a rain when it opens up and is lushly green. Then the oak branches look furry. We also have a bromiliad that is partial to oaks but can actually be found on many, many trees. It's called Spanish moss. That is that gray, witch's-hair stuff that hangs from trees all over the South of the US. Many people think it damages the trees, but bromiliads are not parasites. There are many vines and grasses that grow just about anywhere. We also have that awful kudzu that was imported from Japan as a ground cover for along the highways and has taken over entire forests and even buildings. \n\nIn Feliciana, the corner of the boot where the state line juts east from the Mississippi, there is flora that is typical to the Appalachians. Also in that general area someone has a bamboo grove with hundreds of different kinds of bamboo. In the south we grow rice and sugar cane, primarily, but a tiny bit farther north, soy is grown as well. Keep going north and you have other produce being grown. We can grow citrus and we even have a pretty good vineyard on the North Shore. \n\nHope this helps.

Dude / dudette.\n\nCheck your local search engine.\n\nWatch a plant in your garden, for gawdsakes.  Plants wilt without water, so it's a fair bet that water fills the cells - perhaps the cell walls?\n\nHere's a passage ripped off from a website:\n\nWater acts as a SOLVENT for minerals and stored food that must be moved through the plant. Water evaporation on the leaf surface helps cool the plant during very hot weather in the same way that perspiration keeps us cool. \n\nPlants even require water during winter. Water is absorbed through and stored in roots for winter. When soil is frozen, water movement is very restricted. On windy winter days, leaves of broadleaf evergreens, such as rhododendrons, may curl to reduce water loss. Curling reduces the amount of leaf surface exposed to drying winds, reducing evaporation. Continued water loss may cause tissue to die and turn brown. This kind of plant injury is called desiccation. It is critical that broadleaf evergreens have an adequate supply of soil moisture going into winter.

Okay, for plants to gain energy they break down sunlight through their cells in the way that is called photosynthesis. However, to do this, cells must keep their leaves open and faced towards the sunlight. Transpiration is like us sweating: we loose water in the process to cool down. The heat, air pressure, and solar radiation contribute to this. Because plants need energy, they have to open up and allow transpiration to happen. While they loose water, they gain energy. They just soak up more water from the ground. That is another reason why, if it is in a drought, that plants wither and die. They not only don't have enough water to keep themselves "fed" but the air is soaking up water when they gain energy.

A hydrophyte is a plant adapted to growing in water.

Plants survive by adapting to the environment.  If the local fauna is eating the plant, the plant will develop a toxicity to ward off such animals form dining on the plant or the plant will reproduce in such numbers that a bite here and there doesn't matter.\n\nThe trick comes in when the animal develops a bond with a particular plant and adapts to the toxicity and uses this plant toxin to form its own shield against its predators--such as Monarch Butterflies and Milk weed or Gulf fliterary butterflies and the corky stemed passion flower.

That's going to depend on what kind of plant it is, what kind of soil it's in, and how fast water evaporates.\n\nFor most plants, just keep the soil moist but not marshy.  If you're seeing mold or moss, you're watering too much.

Draw your own. They are not hard. \nH2O\nrain falls, runs into the pond. Sun evaporates the water, cloud forms, rain again.\nCO2\npond plants take in CO2, hey make sugar by photosynthesis using the sun for energy. A byproduct is O2. Pond animals breath the O2 and breath out CO2 which the plants use again.

a wetlands is any land that is covered in water or remains wet Thur out the year, id doesn't matter if it in in a hot tropical area or in Alaska

They don't. \n\nThe stems of water lilies and lotuses for example are very thick corms, thicker than a man's forearm. The stems of bullrushes are as thick as any similar type of plant, the stems of Myriophyllum are at least as thick as your average herbaceous land plant. The stem of bullkelp are thgicker than your arm and easily as thick as the trunk of any tree of equivalent size\n\nWhat makes you think that aquatic plants have thin stems? And can you name any aquatic plants that have stems that are significantly thinner than similar land plants?\n\n\nMaybe then we will have some idea what you are talkng about.

One of the main challenges was reproducing with out the water. This was eventually made possible with spores. However the spoors still needed to be close to the water other wise they would die. Seeds came around later and solved the problem. The seeds provide the nutrients that the plant needs untill it can support itself.

I'd say pretty dang important.\nYou've got competition between plants for resources, like Nitrogen and Phosphorus.  You've got competition between birds for nesting sites.  Fish also play a role here; those that have gills better adapted to salty water can take oxygen out of the water more efficiently than fish that have gills more adapted to freshwater.

They store water inside the shoots,they also have small leaves so they conserve moisture.

Not all plants have roots. The ones that do are the vascular plants which need to take in nutrients passively by means of capillary action and concentration gradients. The plants need their roots to reach down far enough into the vadose zone to get water during times of the year when there isn't much rain and the water table is dropping.\n\nAs already mentioned, roots also stabilize the plant to allow it to grow tall and get sunlight. In many places, competition for sunlight is intense so plants have to grow tall and hold themselves up. Thus, the need for roots.

plants on land have a harder time spreading out their young, look at pollen and seeds.  water plants just release their gametes and they float away

Depends upon the tree and the conditions.  Pussie willow shoots (especially green ones) can be placed in a container of water and will actually grow roots.  These can be planted in the ground to form new trees or bushes.  Weeping willows do the same.\nExperiments have been done with whole evergreens to determine the amount of transpiration (of water vapor) from their needles (the trunk of the tree being placed in an aqueous solution of dilute minerals).  Based upon the oxygen gas generated if the tree is in sunlight), the tree does continue to live for some time.
