Final answer:
The solute potential of the cell is calculated by subtracting the pressure potential from the water potential, giving a result of -0.70 kPa.
Step-by-step explanation:
To calculate the solute potential (Ψs) of the cell, we use the formula that relates water potential (Ψw) and pressure potential (Ψp): Ψw = Ψs + Ψp. The question states that the water potential (Ψw) of a cell is -0.24 kPa and the pressure potential (Ψp) is 0.46 kPa. To find the solute potential, we can rearrange the formula to solve for Ψs giving us Ψs = Ψw - Ψp.
Substituting in the given values: Ψs = (-0.24 kPa) - (0.46 kPa) = -0.70 kPa.
Therefore, the solute potential of the cell is -0.70 kPa.
