Water Wall Xylem Role Adhesion Transpiration Stream  Attraction

Adhesion, the attraction between water molecules and the xylem walls, contributes to capillary action and helps generate tension by pulling inward on the xylem walls as the water column rises.

Adhesion, the attraction between water molecules and the xylem walls, contributes to capillary action and helps generate tension by pulling inward on the xylem walls as the water column rises.

Front the role of adhesion in the transpiration stream 
Back attraction between water and xylem wall (xylem wall and water are polar - intermolecular associations form between them), water moves up in capillary action pulling inward on the xylem wall generating further tension
