From the thermodynamic point of view, a system is a region of space or quantity of matter on which we focus our attention. Systems interact among themselves. The water potential of any system or part of a system that contains water, or could contain water, is a measure of the maximum energy of the water In the system available to do work. Water in the soil-plant-atmosphere-system moves following a water potential gradient which is greater in the soil and lower in the atmosphere. Minerals absorved by the roots in the soil solution follow this water stream, which is called the transpiration stream.
