Which of the following is referred as a model for transpiration?
1 Cohesion Tension Transpiration pull model
2 Cohesion Adhesion Transpiration pull model
3 Tension Transpiration pull
4 All of the above
Explanation:
Most researchers agree that water is mainly 'pulled' through the plant, and that the driving force for this process is transpiration from the leaves. This is referred to as the cohesion tension-transpiration pull model of water transport.

Statement A : Water is absorbed along with mineral solutes, purely by diffusion. Statement B : Once water is absorbed by the root hairs, it can't move deeper into root layers.
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both statements are correct.
4 Both Statements are incorrect.

Water loss in its liquid phase from special openings of veins near the tip of grass blades is termed as ____
1 Guttation
2 Exudation
3 Girdling
4 Transpiration
Explanation:
Effects of root pressure is observable at night and early morning when evaporation is low, and excess water collects in the form of droplets around special openings of veins near the tip of grass blades, and leaves of many herbaceous parts. Such water loss in its liquid phase is known as guttation.
