Summary Introduction
Introduction: Water is the main component in the bodies of animals. Many solutes ions like Na+ and K+ are dissolved in the water of an animal’s body. Water and ions maintain the homeostasis of the organism.

Increasing the concentration of solutes increases osmotic potential, hence water potential decreases.
A. Agree, because presence of solutes increses osmotic pressure and thus osmotic potential.
C. Agree, because they just represent the same values.
D. Disagree, because it is the decrease in water pressure that decreases osmotic potential.
B. Disagree, because presence of solutes increases osmotic pressure which decreases osmotic potential.
