Answer 1

Answer - Properties by which water moves through are : Adhesion, Cohesion, Evaporation and surface tension. Explanation of each property is as follows:

Adhesion :
Adhesion is the mechanism by which it facilitates the force required to pull water from the roots by capillary action. How does this takes place, water molecules adhere to the cell wall of plants and work against the gravitational force to pull water upper part of the tube in the xylem. Through this, water reaches till leaves.

Cohesion:
In the process of cohesion the mechanism by which water makes its way through the plants happens by water molecules staying close to each other and cumulative action of hydrogen bonds between water molecules.
Cohesion is a property or mechanism where plant draws the water upwards from root with the help of stem's transport system till the leaf.

Evaporation :
This cohesion process is supported by the tension created in water molecules due to the process of evaporation.

Surface tension :

This is also a very important property of water. Water has high amount of surface tension property which helps to hold the surface against a external force to create a capillary action.

So, all these 4 properties of water work together and make it possible.
