Detailed explanation-1: -There’s moisture naturally found in potatoes, and moisture is drawn to higher concentrations of salt. (This is a process called osmosis.)

Detailed explanation-2: -The potato in the salt water shrinks because water moves from the potato into the more concentrated salt water. In contrast, water moves from the less concentrated distilled water into the potato causing it to expand.

Detailed explanation-3: -Nothing will happen as the cells of boiled potato are already dead and the selective permeability features of cell membrane doesn’t remains valid. So, no osmosis neither movement of water will take place. Q.

Detailed explanation-4: -Osmosis refers to the movement of water molecules across a membrane trying to achieve equilibrium. Because there are no salts in distilled water, there is a higher concentration of water molecules in the distilled water compared to inside the potato. Therefore water moves INTO the potato.

Detailed explanation-5: -In a highly concentrated salt solution, water is present at a low concentration as compared to the concentration inside the potato cells. This leads to loss of water from cells of potato and potato is plasmolysed.
