Detailed explanation-1: -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-2: -Normally, plants use osmosis to absorb water from the soil. However, when you use salt water to water a plant, the plant is unable to perform osmosis because the water is too dense. What ends up happening is that water is actually drawn out of the plant, dehydrating it, and causing it to cripple.
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 we place a cell in the hypertonic solution like in sugar or salt solution, the cell will shrink. It is because the movement of water takes place from lower solute concentration to higher solute concentration i.e from inside sugar solution to attain equilibrium. It results in shrinkage of the cell.
