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 |
