Detailed explanation-1: -Movement of water into a cell is called as endosmosis and movement of water out from a cell is called as exosmosis. So, a cell placed in strong salt solution will shrink because water comes out by exosmosis.

Detailed explanation-2: -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-3: -The salt solution being hypertonic, the water potential of the salt solution is less than that of the cytoplasm of the cell. Hence water comes out of the cell through osmosis and protoplast shrinks.

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.

Detailed explanation-5: -If the solution outside of the cell is hypertonic, then it is more concentrated in solute than the inside of the cell. As a result, water will flow out of the cell and into the hypertonic solution due to osmosis, thereby causing the cell to shrink.
