Which of the following physical properties of water provides the 'tensile strength' required for the transpirational pull?
Show answer and explanation
Correct answer: Guttation in herbaceous plants
Root pressure is a positive pressure developed due to active absorption of ions. In conditions of low transpiration, it causes 'guttation'—the loss of water in liquid form through hydathodes near the leaf tips.
