System 1 has a water potential of ‒65 MPa. System 2 has a water potential of ‒45 MPa. System 3 has a water potential of 15 MPa. Water will flow from system _______ to system _______.
A) 1; 2
B) 2; 3
C) 3; 1
D) 2; 1

Question

Quizplus · Accepted Answer

Water flows from areas of higher water potential to areas of lower water potential. System 3 has the highest water potential (15 MPa), so water will flow from system 3 to system 1, which has the lowest water potential (‒65 MPa).

System 1 Has a Water Potential of ‒65 MPa
