Detailed explanation-1: -If a cell is placed in an isotonic solution, there will be no net flow of water into or out of the cell, and the cell’s volume will remain stable. If the solute concentration outside the cell is the same as inside the cell, and the solutes cannot cross the membrane, then that solution is isotonic to the cell.

Detailed explanation-2: -If the concentration of solution inside the cell and outside the cell is same, there will be no net movement of water molecules. Such type of solution is called isotonic.

Detailed explanation-3: -when both inside and outside of a cell have the same amount of water it is said that the cell has reached a state of equbilrium .

Detailed explanation-4: -If the water potential on each side of a cell membrane is the same, there is NO NET MOVEMENT of water across the membrane.

Detailed explanation-5: -Explanation: At equilibrium, the pressure potential inside the cell remains zero. There is only pressure potential when water enters a plant cell and pushes against the cell wall to create pressure.
