Cell- To- Cell Water Movement Always Occurs From

Question

Cell- to- cell water movement always occurs from
A) lower to higher water potential.
B) higher to lower water potential.
C) lower to higher solute potential.
D) higher to lower solute potential.
E) higher to lower pressure potential.

Accepted Answer

Cell-to-cell water movement always occurs from higher to lower water potential. Water moves from an area of higher water potential to an area of lower water potential, just like objects roll downhill from a higher altitude to a lower altitude. Water potential is affected by solute potential (dependent on solute concentration) and pressure potential (dependent on pressure exerted on the solution by the surrounding environment). However, in general, water moves from an area with higher water potential to an area with lower water potential regardless of the cause of the difference in water potential.
