Question

water potential is the potential energy for water to move from one area to another. water always moves from a high water potential area to a lower water potential area. according to the water potential formula, which factors affect the water potential?
a) pressure and the amount of solute
b) surface area and depth
c) volume and temperature
d) speed and concentration

Explanation:

Water potential in biological systems is defined by the formula $\Psi = \Psi_s + \Psi_p$, where $\Psi_s$ is solute potential (dependent on the amount of solute) and $\Psi_p$ is pressure potential (dependent on pressure). The other listed factors do not directly affect water potential as defined by the standard formula.

Answer:

a) Pressure and the amount of solute
