Positive water potential is placed on the left side of the tube by increasing Ψp such that the water level rises on the right side. Could you equalize the water level on each side of the tube by adding solute, and if so, how?

The transportation of water, nutrients, and the products of photosynthesis are facilitated by various plant structures such as; roots, leaves, and stems. The vascular tissues like phloem and xylem are mainly responsible for this specific purpose. Transportation of water and nutrients are primarily influenced by evapotranspiration, water potential, and stomatal regulation.

Water potential can be described as the comparison between the potential energy of water in a given system and the pure water at the same temperature and pressure. The factors that affect water potential are solutes, gravity, pressure, and matric potential. The water always flows from a higher level of water potential to a lower level of total water potential.

When a solute is added to the side of the tube having lower water potential can allow water to move from the level of higher water potential to the level of lower water potential. Therefore, the water level can be balanced by adding the solute to the left side of the tube. This will result in the movement of water toward the left until the water levels are equal on both sides of the tube.
