Question

Solute potential is

• A. decrease in magnitude of 𝚿w due to the dissolution of solute
• B. Magnitude of change in the 𝚿w due to the mechanical pressure
• C. Component of 𝚿w contributed by the application of pressure by the solution
• D. Pressure exerted by the protoplast due to the entry of water into the cell

Answer 1

The correct option is A decrease in magnitude of 𝚿w due to the dissolution of solute

Component of 𝚿w contributed by the application of pressure by the solution is the pressure potential (𝚿p).
Magnitude of change in the 𝚿w due to the mechanical pressure is the pressure potential (𝚿p).
Decrease in magnitude of 𝚿w due to the dissolution of solute is the solute potential (𝚿s).
Pressure exerted by the protoplast due to the entry of water into the cell, against the rigid cell wall is the turgor pressure (TP). It is responsible for the enlargement and extension growth of cells.
