In plant-water relationships, symbol `'Psi_w'` is used to represent

Options

A. Osmotic pressure
B. Water potential
C. Solute potential
D. Osmosis

Answer

B

Explanation

Water potential is the potential energy of water per unit volume relative to pure water in reference conditions. Water potential quantifies the tendency of water to move from one area to another due to osmosis, gravity, mechanical pressure, or matrix effects such as surface tension. Water potential is typically expressed in potential energy per unit volume and very often is represented by the Greek letter
