Water is lost through the stomata by evaporation        SO 

Water is gained through the root hair cells by osmosis

LOW HUMIDITY -> INCREASED WATER POTENTIAL -> INCREASED TRANSPIRATION

HIGH TEMPERATURE -> INCREASE IN EVAPORATION -> INCREASE TRANSPIRATION

MORE WIND -> MORE DIFFUSION & EVAPORATION -> INCREASE TRANSPIRATION

MORE LIGHT -> MORE PHOTOSYNTHESIS(stomata open) -> INCREASE TRANSPIRA.
