Chapter 34.1, Problem 1SB
Summary Introduction
To review:
The water potential and its importance in plant cells.
Introduction:
Water potential describes how water molecules freely move in a particular environment or system. It is denoted by kilopascals (kPa) or psi (ѱ). The value of water potential always remains negative but it has a maximum value of 0, which is considered as the purest form.
