Explain capiility theory of water translocation

$\underline\bold\blue{Answer}$

According to this theory, water is translocated because water molecules adhere to the surfaces of small, or capillary, tubes. This adhesion causes water to somewhat creep upward along the sides of xylem elements. In glass tubes this upward movement is visible as the curved or crescent-shaped (concave) meniscus. However, it was shown that capillarity (or capillary rise) alone in tubes of similar diameter as that of a xylem element raises water less than 1 meter.

Answer 2

Answer:

most accepted theory of ascent of sap in transpiration pull theory. upward conduction of water in the form of dilute solution of minerals ions from root to aerial part is called ascent of sap
