Detailed explanation-1: -When cells are placed in a pure water environment, water floods the cell and causes it to burst.

Detailed explanation-2: -Salt Sucks, Cells Swell 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-3: -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-4: -If you water a plant with salt water, it will wilt, and will eventually die. This is due to the fact that the salt water is a hypertonic solution when compared to the plant cells, and water inside the plant cells will diffuse by osmosis out of the cells in order to reduce the concentration of the salt solution.

Detailed explanation-5: -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.
