Answer:
In case of plants surface tension help to support the transpiration pull.
Explanation:
Surface tension is a force that hold the molecules in the surface to minimize the surface area.
During evaporation of excess amount of water from the stomata of leaves of plants by transpiration a surface tension is generated.
The generated surface tension helps to maintain the water column within the xylem tissue by the absorption of water from the soil by the roots.
