17.1.1: Water Potential
What does a negative water potential mean?
Transport of Water and Solutes in Plants
Further compared to other methods, no precise temperature controls are needed.
Ans: Pressure increases the kinetic energy of the water molecules present in water and hence increases the water potential.
In a plasmolysed plant cell, the turgor pressure is zero.
Water Potential, Diffusion And Active Transport
There are reasons to look at secondary measurement methods, though.
Solutes Ψ s , pressure Ψ p , and gravity Ψ g influence total water potential for each side of the tube Ψ total right or left and, therefore, the difference between Ψ total on each side Δ.
When a total water potential Ψ is lower outside the cells than inside, water moves out of the cells and the plant wilts.
