Detailed explanation-1: -Since water is attracted to other molecules, adhesive forces pull the water toward other molecules. Water is transported in plants through both cohesive and adhesive forces; these forces pull water and the dissolved minerals from the roots to the leaves and other parts of the plant.
Detailed explanation-2: -Hydrogen bonds cause water to be exceptionally attracted to each other. Therefore, water is very cohesive.
Detailed explanation-3: -Which property of water allows it to move upward from the roots of a tree to its leaves? As water evaporates from the leaves of trees, the property of cohesion (attraction to another water molecule) allows the water molecules leaving the plant to pull molecules upward because they are attracted though hydrogen bonds.
