If you uproot a plant from the soil, its leaves soon wilt.

This is because the turgidity of the leaf cells keeps the leaf straight and extended. Turgidity is obtained by the intake of water from the soil which balances the transpiration rate. Thus when a plant is uprooted, its leaves soon wilt due to the unavailability of water.
