Answer :
Yes , when potatoes are in the ground, they swell with water when it rains.
Potatoes, like any other plant, need water to grow, so when it rains, the water soaks into the ground and the potatoes absorb the water via osmosis.
Osmosis is the process b which water molecules move from an area of high concentration to an area of low concentration through a selectively permeable membrane.
In potatoes, this membrane is the cell wall. When rainwater enters the soil, it moves from an area of high concentration to an area of low concentration, and it eventually makes its way into the cells of the potato plants.
This is advantageous because it helps the potatoes to grow larger and develop a better taste. However, if there is too much rain, the potatoes can become waterlogged, which can lead to disease and rotting
In an isotonic solution, the concentration of solutes inside the cell is equal to the concentration of solutes outside the cell. This means that there is no net movement of water across the cell membrane, so osmosis does not occur. Therefore, the cell remains the same size.
