science help: What is the effect of salt water to plants? - Help.com

i thought that helped great! thank you so much…now i can get my A+ on my assignment…cuz this is pretty much exactly what my extension was…thanks again this was a huge help xD

What happens is that salt molecules are much larger than water molecules, so they can’t enter the plant. But permeable organic membranes, like the roots of plants that let water in, are subject to a force called “osmosis”…basically it’s a force that wants everything on one side of the membrane to be the same as everythingon the other side of the membrane. So if there’s salt and water on one side, and water but no salt ont he other, the osmotic force will try to even everything out. But the salt can’t get in. So the membrane just keeps letting more and more water out trying to make the internal saltiness match the external saltiness, but since plants have such a low salt content, they have to give up almost all their water to achieve this, so the die.

That’s not a very good explanation, but I hope it helps.[/quote]

when salt n water mix the salt sucks up all the water and that leave the plants to die because plants cant live without water. so when the plant water is all sucked up the plant dries out and the leaves start to turn brown. im a 5th grader and thats what i think happens to the plants.

ohh
