Question

A cell is in equilibrium with its surrounding at 22°C. The molarity of the surrounding sucrose
solution is 0.7 M. Calculate the solute potential of the cytoplasm of the cell.

Answer 1

• The solute potential of the cell’s cytoplasm is –0.45MPa. The water potential of the surrounding solution is –0.32Mpa. When the cell was first put into the solution, it was flaccid. 1. Since the cell was put into this solution, its solute potential and pressure potential have both risen. 2. The pressure potential of the cell is now +0.32MPa. 3.

Answer 2

A cell is in equilibrium with its surrounding at 22°C. The molarity of the surrounding sucrose

solution is 0.7 M. Calculate the solute potential of the cytoplasm of the cell.
