WebWater can be rise upwards in the absence of roots. When the water potential of the root becomes more negative than the soil, it causes water to move by osmosis into the root from the soil that creates a positive pressure which forces sap up the xylem to wards the leaf. Then the sap will be forced from the leaf through a hydathodes called guttation.
