|
Water will pass from inside the cell to outside by diffusion
|
|
|
Water will enter the cell by osmosis
|
|
|
Salt will escape from the cell through the semipermeable membrane
|
|
|
There will be no movement of substances between the cell and it’s environment

Detailed explanation-1: -Here Water in cells moves toward the highest concentration of salt. As there is more salt in a cell than outside it, the water will move through the membrane into the cell, causing it to increase in size, swelling up as the water fills the cell in its imperative to combine with the salt.
Detailed explanation-2: -Salt triggers osmosis by attracting the water and causing it to move toward it, across the membrane. Salt is a solute. When you add water to a solute, it diffuses, spreading out the concentration of salt, creating a solution.
Detailed explanation-3: -When animal cells are put in salty water, water diffuses/moves out of the cell and the cell shrivels up. When plant cells are put in fresh water, water diffuses/moves into the cell and fills up the central vacuole.
Detailed explanation-4: -Cells placed in a hypotonic solution will take in water across their membrane until both the external solution and the cytosol are isotonic. A cell that does not have a rigid cell wall, such as a red blood cell, will swell and lyse (burst) when placed in a hypotonic solution.
