Which of the following will lead to decrease in water potential? )Addition of solutes - Addition of water ) Increased d) removal of heart
Answers
Solutes reduce water potential (resulting in a negative ) by consuming some of the potential energy available in the water. A low water potential means that water has a low force driving it to move from one area to another. Solute molecules can dissolve in water because water molecules can bind to them via hydrogen bonds. a hydrophobic molecule like oil, which cannot bind to water, cannot go into solution.
The energy in the hydrogen bonds between solute molecules and water is no longer available to do work in the system because it is tied up in the bond. In other words, the amount of available potential energy is reduced when solutes are added to an aqueous system. If the solute concentration of a solution increases, the potential for the water in that solution to undergo osmosis decreases. Therefore, the more solute that is added to a solution, the more negative its osmotic (solute) potential gets. Solute potential decreases with increasing solute concentration; a decrease in causes a decrease in the total water potential. The internal water potential of a plant cell is more negative than pure water; this causes water to move from the soil into plant roots via osmosis.Pressure potential increases as water enter a cell. As water passes through the cell wall and cell membrane, it increases the total amount of water present inside the cell, which exerts an outward pressure that is opposed by the structural rigidity of the cell wall. thus addition of solutes leads decrease in water potential
