Because the saltwater is dehydrating it, just like it will dehydrate humans eventually.
A freshwater paramecium would shrivel in salt water due to a precess called osmosis.
Osmosis is a type of diffusion that occurs in water. If you have a container with two different salt concentrations separated by a fine screen (semipermeable barrier) that will allow water to move back and forth, but not salt, the water will try to move to the side with more salt to dilute that salt. This is what happens to your paramecium. The water inside the paramecium will move outside the paramecium to try to dilute the saltwater, causing the paramecium to shrivel like a ball that has had the air let out.
Further explanation of osmosis can be found at http://en.wikipedia.org/wiki/Osmosis
As a side note, this is why drinking salt water actually dehydrates a person. When you have salt water in your digestive track the water in your body will move into your digestive track to dilute the salt water. The water is then excreted through your urine leaving you with less water in your body then before you drank the saltwater.

∙ 14y agoDue to osmosis. The cell has water in it, cell membranes are permeable, and if you have different salt concentrations across the membrane water will move over in an attempt to even out the balance.
Wiki User
∙ 13y agoThis is because of the process of osmosis. When an animal cell is placed in concentrated salt solution (of lower water potential than the animal cell/ hypertonic relative to the cell), water molecules will leave the cell and move into the salt solution to achieve equilibrium of water potential. This causes the animal cell to decrease in size and shrink. Spikes appear around the cell, and the cell is said to be crenated.

∙ 11y agoSalt water draws the water towards itself. This is because of osmosis, which is the diffusion of water across a cell membrane. The salt water contains less water than the cell. So in order for it to reach equilibrium it draws water from the cell, therefore shrinking the cell.

Why a person could die of dehydration by drinking enough 10 percent salt solution?
The cells in the persons body would try to equalize the concentration on the outside and inside of the cell. This would lead to the cells exposed to the hypotonic solution dehydrating themselves.
Solutions of water and other molecules are found both inside and outside living cells. what term refers to the salt in a solution of salt and water?
Salt is the solute.
What would happen to a salt water plant if you put in fresh water and why?
The plant is most likely to die because the salt water already killed the root cells. It also depends on the concentraition of the plant. some plants are very sensitive when fresh water is placed in ONLY salt water plants
Why will the blood cell shrivel and possibly die inside a hypertonic salt solution?
There was more salt/solute outside of the cell, and the solute "sucks" away the water from the cell;making it shrink and possibly collapse in itself.
Does an egg get bigger if you put it in water?
It has to do with osmosis since their is so much salt in saltwater the salt takes up space so their is more water in the egg so the egg will shrink and their will be more water in the cup so it reaches eqilibrium.
What happens to Carrot cells in salt water?
Carrot cells in salt water shrink in size
What happens to cells in saltwater?
cells shrink because salt water is hypertonic solution.
When a piece of zucchini soaked in a salt water?
The cells in the zucchini shrink because they lose their water.
What would happen if freshwater bacterial cells are placed in salt water?
water leaves the cell causeing the cell to shrink.
Would a carrott shrink or swell in salt water or in fresh water?
shrink in salt water. swell in fresh water.
Why does potatoes get soggy in salt water?
It has to do with hypertonicity between cells. The concentration of water in salt water is lower than the concentration of water inside the potato. So water will move out of the potato and in to the salt water to create equilibrium, causing the potato to shrink.
Why does a naked egg shrink in salt water?
Well, salt is composed of sodium and chlorine. Sodium is also a common element used in shrink rays. Combining it with chlorine allows it to dissolve in water and turn the water into a shrink liquid. Therefore, the eggs shrink after reacting with the shrink liquid.
Do cells shrink in isotonic solution?
No, but in salt solution: Yes.
Will a chicken egg in salt water grow or shrink?
the egg will shrink.
What happens when you drink salty water?
First of all, it won't be pleasant! Secondly, a little will do no harm, but a lot will make you go; mad.
Explain why a carrot feels spongy after being soaked in salt water?
Water moves out of the carrot's cells and into the salt water due the difference in concentration of NaCl. This might account for the spongy-ness of the carrot
Why don't plant cells shrink up like animal cells in a salt solution?
The cell body does shrink, however in plants there is a rigid cell wall framework and this does not shrink with the cell contents.
