$\begin{array}{cccc}& \text{List - I}& & \text{List - II}\\ \text{(a)}& \text{Cohesion}& \text{(i)}& \text{More attraction in}\text{liquid phase}\\ \text{(b)}& \text{Adhesion}& \text{(ii)}& \text{Mutual attraction}\text{among water molecules}\\ \text{(c)}& \text{Surface tension}& \text{(iii)}& \text{Water loss in liquid phase}\\ \text{(d)}& \text{Guttation}& \text{(iv)}& \text{Attraction towards}\text{polar surfaces}\end{array}$

Choose the correct answer from the options given below :

• A. $\left(a\right):\left(ii\right);\left(b\right):\left(i\right);\left(c\right):\left(iv\right);\left(d\right):\left(iii\right))$
• B. $\left(a\right):\left(ii\right);\left(b\right):\left(iv\right);\left(c\right):\left(i\right);\left(d\right):\left(iii\right))$
• C. $\left(a\right):\left(iv\right);\left(b\right):\left(iii\right);\left(c\right):\left(ii\right);\left(d\right):\left(i\right))$
• D. $\left(a\right):\left(iii\right);\left(b\right):\left(i\right);\left(c\right):\left(iv\right);\left(d\right):\left(ii\right))$

Answer 1

The correct option is B $\left(a\right):\left(ii\right);\left(b\right):\left(iv\right);\left(c\right):\left(i\right);\left(d\right):\left(iii\right))$

Cohesion, adhesion and surface tension are the main properties of water on which transpiration driven ascent of sap depends.

Cohesion is the mutual attraction between water molecules.

Adhesion refers to the attraction of water molecules to polar surfaces such as the surface of tracheary elements of xylem.

Surface tension is that the water molecules are attracted to each other in the liquid phase more than to water in the gas phase.

Loss of water in its liquid phase through hydathodes present in the margins and tips of grasses and many herbaceous plants is known as guttation.
