A column of water within xylem vessels of tall trees does not break under its weight because of

A

dissolved sugars in water

B

tensile strength of water

C

lignification of xylem vessels

D

positive root pressure

Text Solution

Verified by Experts

The correct Answer is:
B
A column of water within xylem vessels of tall trees does not break under its weight because of high tensile strength of water, i.e., an ability to resist a pulling force. This high tensile property depends on cohesion, adhesion and surface tension property of water. Due to these forces only transpiration driven ascent of xylem sap occurs.
