Water Potential, or the Tendency of a Solution to Take

question 245

Multiple Choice

Water potential, or the tendency of a solution to take up water from pure water (i.e., water with no solutes) is determined by both solute potential and pressure potential.Which of the following is true regarding the relationship between solute potential and pressure potential?

• A) As solute potential increases, pressure potential also necessarily increases.
• B) Pressure potential has little effect on water potential.
• C) Water potential can be calculated by dividing solute potential by pressure potential.
• D) Solute potential and pressure potential can vary independent of each other.
• E) Water potential is ultimately determined more by solute potential than by pressure potential.
