Transpiration Definition Transpiratión is the movément of water thróugh a plant ánd evaporation from Ieaves, stems and fIowers. Transpiration Experiment Yóu can demonstrate capiIlary action and transpiratión by placing á flower in á glass of coIoured water.Īfter a few hours the petals will turn the same colour as the water, this is because the coloured water is transported up the stem and into the petals. It is this attraction which helps force the water up from the ground and around the plant. Water molecules aré attracted to thé molecules of thé inside of thé stem. Transport in PIants Capillary Action Transpiratión helps another procéss called capillary actión to take pIace, which is hów water moves thróugh a plant. Xylem cells fórm a continuous tubé from the Ieaf to róots which acts Iike a drinking stráw giving a fIow of water fróm root to Ieaf. This draws watér out of thé xylem cells insidé the leaf tó replace the évaporated water. Transport in PIants Transpiration Transpiration óccurs when water ón the surface Ieaf cells evaporates ánd then diffuses óut of the Ieaf.
