Answer:
The movement of water up in the plants depends upon the adhesion and cohesion of the molecules and this would get reduced if water becomes non-polar, and thus, it would become difficult for the water to move up in the plants.
The non-polar bonds are much weaker in comparison to polar bonds, and thus, the molecules of water would combine together in a weaker manner. If the molecules of water become non-polar, then it would lose its tendency to form hydrogen bonds, as the formation of hydrogen bonds only takes place between the molecules that are polar.
