Plants use adhesion and cohesion to produce an affect called capillary action which will help move materials upward and circulate the substances throughout the plant.

First, the adhesion makes the molecules of water stick to the walls of the plants roots and leaves. Then the cohesion joins the molecules of water together to help them move up the walls of the plants roots and leaves.
Adhesion and Cohesion
Really need help!
it depends on the solid with which the liquid comes in contact, if the adhesion is stronger the liquid wets the solid else i t cannot ; eg;- in the case of water and glass the adhesion is much stronger than cohesion ,on the other hand the cohesion is greater if you consider the case of water and certain leaves(in which water cant wet them).
In Volvox, cells are held together by tight junctions and cell adhesion proteins. These structures provide structural support and help maintain the colony's shape. Additionally, extracellular matrix materials secreted by the cells also play a role in cell cohesion.
Two important phenomena that occur in plant leaves to help with water transportation in xylem tissues are transpiration and cohesion-adhesion. Transpiration is the process where water evaporates from the leaves and creates a force to pull more water up from the roots, while cohesion-adhesion are forces that allow water molecules to stick together and to the walls of xylem vessels, aiding in their movement upwards.
The properties of adhesion and cohesion in water molecules allow for capillary action, enabling water to move up the roots of a tree. Adhesion causes water molecules to stick to the walls of the plant's xylem vessels, while cohesion keeps water molecules together, allowing them to be pulled up as a column. Transpiration, the process of water evaporating from the leaves, also helps to create a low pressure in the leaves, pulling water up the plant.
All plants give us materials, what materials were you specifically wanting to know about. If you want our help please ask questions that are specific.
Mercury is a metal unlike water which have hydrogen bonding. Mercury does not wet most substances, because of its high cohesion and low adhesion to the glass mercury will not wet glass. Cohesion, along with adhesion(attraction between unlike molecules), can help explain mercury phenomena. Mercury has a surface energy over 6 times greater than that of water so there is a much greater attractive force between the atoms of mercury than between the molecules of water, so mercury does not wet glass.
B. Capillary action. Capillary action, along with cohesion and adhesion forces, allows water to move upwards through the xylem in the tree, from the roots to the leaves. These forces help counteract gravity and allow water to reach the top of tall trees.
it will help because it will be a huge celebration
