Detailed explanation-1: -A cell place in salty solution would loose water as water will move from cell to surrounding hypertonic medium by the process of osmosis causing the cell to shrivel up.

Detailed explanation-2: -The added salt makes the solution hypotonic compared to the cell. Water will enter the cell by osmosis. Water would leave the cell by osmosis, causing the volume of the cytoplasm to decrease.

Detailed explanation-3: -Water in cells moves toward the highest concentration of salt. If 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-4: -The water potential of the salt solution, being hypertonic, is less than that of the cytoplasm of the cell. Hence, water comes out of the cell through osmosis and protoplast shrinks. This process is called as plasmolysis.

Detailed explanation-5: -Similarly, if there is a higher concentration of dissolved salt outside of the cell (a hypertonic environment), then H20 will diffuse “out” from the cell and the cell will dehydrate and shrink and cellular metabolism will cease.
