Detailed explanation-1: -Final answer: When the cell when it is placed in salt solution, it will shrinks.
Detailed explanation-2: -For example, a solution containing 10% salt is hypertonic. When a cell is placed in a hypertonic environment, there is a net movement of water to the outside of the cell (from the higher water environment inside the cell). The cell shrinks in response.
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: -When a cell is placed in a beaker of 10 % saline solution. We know that water moves from a higher concentration to a lower concentration. This means that water will move towards more concentration of solvent. Therefore, water will move inside the cell as it has more water (solute).
