What happens when regular water is replaced with salt water for plant consumption?

In order to absorb water the concentration of the cell sap in the plant, especially in the root cells, must be at a lower level than that of the watery solution in the soil. When you put any water soluble salt in the water and ‘offer’ it to the plant, then due to the higher concentration of the salt outside; the water from the plant will be ‘sucked out’ resulting in the wilting and then death of the plant. It is called reverse osmosis. The plants and the trees that grow in the salty soil always have their cell sap concentration greater than the surrounding salty water. This is ecological adaptation. In short, the flow of water, in the living plants, is from the solution of lower concentration to the solution of higher concentration. This is Proper OSMOSIS.\nNow tell me can you drink water with very high amount of table salt in it?

, you can´t make seawater with regular salt because of the contents but if you want to make a equivilant it would be 2/4 cups of salt and 2 cups of water\n \nHere are some other facts for your sister to use in her writen report of the project.\nSeawater has one of the most stable constitutions, varying only in a few places in its 77% coverage of the earth's surface. This factor makes keeping marines more difficult than freshwater species as the fish involved have little tolerance to changing conditions - they never encounter any - but, advantageously it means that all marine fish will be at home in one common type of water. \n\nExcept for those few aquarists who have access to natural tropical seawater, the majority of marine fishkeepers have to rely on preparing their own synthetic variety using commercially-available salt mixes.\n\n \nTo make sure the water is mixed to the correct conditions, test the 'strength' of the mix by measuring the Specific Gravity (S.G) of a sample. \nIn Nature, this approximates to 35 ppt (parts per thousand) or, in practical terms 35 grams of salt per litre of water, approximately S.G of 1.025; in this example, the S.G of the sample reads 1.024 which is satisfactory for a reef tank but could be lower (1.021-1.023) for a 'fish only' collection.\nIt is important to measure the S.G. when the water is at the correct temperature (75oF) and thankfully most hydrometers offered at the aquatic outlets are calibrated at this value. \n\n\n\n\nSynthetic seawater should be mixed in clean plastic containers and aerated for at least 24 hours before use.\n\nOne of the curses of the marine aquarium (not helped either by the intense lighting found on most systems) is unwanted algae; this is further encouraged by phosphates and nitrates found in the water used to make the seawater. \nAlways use a salt-mix that is labelled 'phosphate and nitrate free' and also make sure that water used is also free of these substances too.\n\nSource water can range from absolutely free of anything tapwater (via Reverse Osmosis treatment), nitrate removed by a Nitragon unit or phosphate removed by using RowaPhos(tm) in a filter.\nAdditionally, clean rainwater can be used.\n\nNitrate levels can be kept to a minimum im the aquarium by the action of use anaerobic de-nitrifying bacterial colonies within Living Rock, and by regular partial water changes. The build up of nitrate can also be minimised by using a protein skimmer to remove organic substances from the water before the nitrite-forming and nitrate-converting bacteria can get their hands on them. \n\nKeep a check on pH and nitrate levels: rising nitrate levels and a falling pH means it's time for a water change. Whilst nitrate levels in a fish-only collection can be allowed to rise, invertebrates appreciate really low levels (zero, preferably

Sea water being salty, is not drinkabl. With the peoper apparatus, you can ue the sun to evaporate the sea water. Then you have to catch it as it condenses. The salt does not evaporate.Now it is drinkable.  Mineral water essentially is water from the ground that has minerals from the earth dissolved in it. When this is evaporated the minerals do not evaporate either. You can get drinkable water from sea water, but not mineral water.

Your getting rid of water and salt. Your body will need water and electrolytes to survive. These cells shrivel up due to a mostly hypotonic solution.

Saltwater is isotonic to a cell assuming that it has a balanced osmolarity for the particular cell.  Fresh water has essentially no ionic component, and as such will cause the cell to take up water in an attempt to balance the gradient.

Water wastage will never be a problem, EVER.\nWe have abundant resources, and if those ever began to dry up, which they won't because of rain collection, we have desalinization plants that filter the salt out of ocean water and purify it so it is drinkable.\n\nBy the way I love that word, "wastage."

Osmosis would literally suck all the water out of the fish's body therefore dehydrating it.  It would be like taking a saltwater fish and putting it in freshwater or visa versa.  The fish may live briefly before it's metabolic pathways shut down due to lack of water.

I'm going to assume you are talking about plants. It depends. More transpiration means more water flows through plants, so of course more nutrients will enter the plant tissue. However, the amount that is actually absorbed for use by the plant is controlled by the plant cells.... excess minerals are usually stored.

It's the removal of salt from water.  A desalination plant removes salt from water for people to use - usually through reverse osmosis.

Some water is essential for all plant growth, though necessary amounts vary for individual species. Too little water will cause the plant to wither and die, and too much water will waterlog the roots and rot them, killing the plant.

because the salt u use in the kitchen does not contain all the particals in the sea water like sodium sulphate magnesium sulphate etc because they are removed in the process  of making the salt and some times the salt it cut down from deep earth and they are also cleaned by removing the toxic particles and iodised which may alter the sea water salt from earth solt altho the main component of salt is Na Cl it has other particals such as iodine and k+ irons Fe ect...

The reason why salt water kills the plant is because the concentration of osmolites (salt disolved in water) is so high that it will draw the water out of the roots into the soil solution (a process called osmosis). It will dry the plant. The same happens with too much fertilizer. And the exact same thing happens with sugar, which is also a very powerfull osmolite.\nThe sugar molecule cannot be absorbed by roots, so that won't help the plant, even at non restrictive concentrations.\nAloe vera, on the other hand, is a dessert plant and should resist some concentration of osmolites in the solution (that is, howevere, my guess). You can probably test how much sugar and/or salt it resists...keep in mind, though, that if you water the plant with sugar water (or saltwater) once, and it dries up, the sugar will remain in the soil, so don't water it again with sugar water because you will be doubling th concentration.

Seawater can be turned into drinkable (potable) water by one of a number of desalination processes. Otherwise, it should not be drunk because of its high dissolved mineral content. In the long run, more water must be expended to eliminate these minerals (through excretion in urine) than is gained from drinking the seawater itself.

they have a natural process of osmosis that stabalises them with the water and salt content of the sea when they drink the water so that they get enough water in their bodies while being able to live in the salty sea.

The sun causes the water to evaporate leaving the salt behind.

The minerals and salts in the water dehydrates the body the more water you drink.

(m)\n\nEveryone who has been to the beach knows that seawater is salty. Everyone also knows that fresh water in rain, rivers, and even ice is not salty. Why are some of Earth’s waters salty and others not? There are two clues that give us the answer. First, “fresh” water is not entirely free of dissolved salt. Even rainwater has traces of substances dissolved in it that were picked up during passage through the atmosphere. Much of this material that “washes out” of the atmosphere today is pollution, but there are also natural substances present.\n\nAs rainwater passes through soil and percolates through rocks, it dissolves some of the minerals, a process called weathering. This is the water we drink, and of course, we cannot taste the salt because its concentration is too low. Eventually, this water with its small load of dissolved minerals or salts reaches a stream and flows into lakes and the ocean. The annual addition of dissolved salts by rivers is only a tiny fraction of the total salt in the ocean. The dissolved salts carried by all the world’s rivers would equal the salt in the ocean in about 200 to 300 million years.\n\nA second clue to how the sea became salty is the presence of salt lakes such as the Great Salt Lake and the Dead Sea. Both are about 10 times saltier than seawater. Why are these lakes salty while most of the world’s lakes are not? Lakes are temporary storage areas for water. Rivers and streams bring water to the lakes, and other rivers carry water out of lakes. Thus, lakes are really only wide depressions in a river channel that have filled with water. Water flows in one end and out the other. \n\nThe Great Salt Lake, Dead Sea, and other salt lakes have no outlets. All the water that flows into these lakes escapes only by evaporation. When water evaporates, the dissolved salts are left behind. So a few lakes are salty because rivers carried salts to the lakes, the water in the lakes evaporated and the salts were left behind. After years and years of river inflow and evaporation, the salt content of the lake water built up to the present levels. The same process made the seas salty. Rivers carry dissolved salts to the ocean. Water evaporates from the oceans to fall again as rain and to feed the rivers, but the salts remain in the ocean. Because of the huge volume of the oceans, hundreds of millions of years of river input were required for the salt content to build to its present level. \n\nRivers are not the only source of dissolved salts. About twenty years ago, features on the crest of oceanic ridges were discovered that modified our view on how the sea became salty. These features, known as hydrothermal vents, represent places on the ocean floor where sea water that has seeped into the rocks of the oceanic crust, has become hotter, and has dissolved some of the minerals from the crust, now flows back into the ocean. With the hot water comes a large complement of dissolved minerals. Estimates of the amount of hydrothermal fluids now flowing from these vents indicate that the entire volume of the oceans could seep through the oceanic crust in about 10 million years. Thus, this process has a very important effect on salinity. The reactions between seawater and oceanic basalt, the rock of ocean crust, are not one-way, however; some of the dissolved salts react with the rock and are removed from the water.\n\nA final process that provides salts to the oceans is submarine volcanism, the eruption of volcanoes under water. This is similar to the previous process in that seawater is reacting with hot rock and dissolving some of the mineral constituents.\n\nWill the oceans continue to become saltier? Not likely. In fact the sea has had about the same salt content for many hundred of millions if not billions of years. The salt content has reached a steady state. Dissolved salts are being removed from seawater to form new minerals at the bottom of the ocean as fast as rivers and hydrothermal proce
