Answer:
The water potentials (Ψ) of the cell and its surroundings are the same.
Explanation:
When a cell is kept in hypotonic surroundings such as distilled water, the osmotic movement of water occurs towards the cell. The entry of water makes the cell swell up and it becomes turgid. Water potential is determined by solute and pressure potentials mainly. Here, the solute potential of the cell and the distilled water was different resulting in differences in their respective water potential values which in turn served as a driving force for endosmosis.
When the cell is fully turgid, the solute concentration of the cell and the surrounding distilled water become equal to each other. Under these conditions, the water potential of the cell and distilled water are the same.
Potassium is 10 to 20 times higher inside the cell, and sodium is 10 to 20 times higher outside the cell. The potential difference across the cell is important in several processes such as transmission of nerve impulses and maintain the ion balance.
The sodium concentration higher out side and potassium higher inside the cell then it moves two potassium into the cell where potassium levels are high and pump three sodium ions out of the cell and into the extracellular fluid.
This is due to action of membrane active transport system which pumps sodium out of the cell and potassium into it. Both helps in body maintain flid and blood volume so it can function normally.

Molecules are moving because they have energy. As the liquid cools down, the amount of energy is reduced and the molecules start to move slower. When the water temperature reaches around 0°C, the molecules stick together and form a solid – ice. Even in this solid stage, the molecules are still moving – we just can’t see it.
