Detailed explanation-1: -If a cell is placed in a hypertonic solution, water will leave the cell, and the cell will shrink.
Detailed explanation-2: -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-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: -Hypertonic-A solution is described as a hypertonic solution to a cell if its solute concentration is higher than inside the cell. Thus, the solute is unable to cross the membrane and stays outside. Hence the net flow of the water too is outwards, where there is more solute, causing the cell to lose volume and shrink.
Detailed explanation-5: -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.
