    Pure water

2% sucrose solution

4% glucose solution

10% sodium chloride solution

Water potential is the chemical potential of the water

Solute potential is always negative

    Pressure potential is zero in a flaccid cell

    Water potential equals solute potential in a fully turgid cell

Increased stomatal aperture during the day

Accumulation of organic acids at night

Reduced transpiration rates

Increased root-to-shoot ratio

    Reversible osmotic potential in the cells

    Reversible turgor pressure in the cell of their pulvini

    Due to less pressure potential in the cells

Presence of less turgidity in the cells

Liquid droplets

Water vapor

Ice crystals

Water soluble salts

Transpiration pull

Root pressure

Capillary action

${\psi _w} = {\psi _s} - {\psi _p}$

${\psi _s} = {\psi _w} + {\psi _p}$

${\psi _w} = {\psi _s} + {\psi _p}$

${\psi _p} = {\psi _w} + {\psi _s}$
