Water moves

(1) Down a gradient of solutes

(2) Down a gradient of free energy

(3) Above a gradient of water

(4) Above a gradient of pressure

(1) Denoted by Greek symbol psi

(2) Expressed in pressure units such as Pascals (Pa)

(3) At standard temperature not under any pressure, is taken zero

(4) Always negative or zero

(1) Dissolution of a solute causes lowering of water potential

(2) Increase of solute causes increase of water potential

(3) Increase of solute causes decrease in osmotic pressure

(4) Increase of solute causes increase in solute potential

(1) All the solutes have lower water potential than pure water given that solution is under external pressure

(2) All the solutions have lower water potential than the pure water

(3) All the solutions have higher water potential than the pure water

(4) All the solutions have lower water potential than pure water unless solution is under such external pressure which is more than the solute potential

(1) More when solute is more

(2) Less when solute is less

(3) Always negative

(4) All of these

(1) Solute potential is more than water potential

(2) Water potential more than solute potential

(3) Solute potential is less than water potential

(4) Water potential is equal to solute potential

(1) Positive water potential when cells get turgor pressure

(2) Negative water potential when water is transported up a stem

(3) Negative pressure is developed in the cell dure to turgor pressure

(4) Both A and B

(1) Turgor pressure

(2) Wall pressure

(3) Osmotic Pressure

(4) Solute pressure

(1) Freelly permeable

(2) Impermeable

(3) Semipermeable

(4) Selectively permeable

(1) Solute potential is contributed by cytoplasm

(2) Solute potential is contributed by cytoplasm and as well as vacuolar sap

(3) Solute potential is because of vacuolar sap only

(4) Solute potential is caused by nucleoplasm
