Solution

Capillarity
Capillarity is a method rarely used by plants for the ascent of sap.
Xylem channels function as fine capillary tubes through which water rises automatically due to the force of surface tension.
However, the xylem vessels of roots are not in direct contact with soil water, which is essential for the occurrence of capillarity.
Hence, the force of capillarity does not operate in plants because the xylem of the root does not dip in soil water.
