name the factors that influence water potential?
Answers
Answer:
Water potential: Water potential is a fundamental concept to understand water movement. It is denoted by yro. The pure water has the maximum water potential due to its greater kinetic energy. As both are related with the movement of water, water potential is expressed in pressure units such as pascal (Pa).
The water potential of pure water at standard temperatures, which are not under any pressure, is taken to be zero.
Solute potential (ys) and pressure potential (yp) are the two main components that affect water potential.
(a) Solute potential: All solutions have a lower water potential than pure water. The magnitude of this lowering due to dissolution of a solute is called solute potential devoted by p. The more the solute molecules, the lower is the ys.
For a solution at atmospheric pressure
|/W = |/S
