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.

Adhesion and Cohesion
Adhesion and cohesion are crucial for plant water movement through capillary action. Cohesion allows water molecules to stick together, creating a continuous column of water in the xylem vessels. Adhesion enables water to adhere to the walls of these vessels, helping to counteract gravity and facilitating the upward movement of water and nutrients from the roots to the leaves. Together, these forces ensure efficient transport essential for plant health and growth.
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.

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.
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).
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.
Cohesion and adhesion play crucial roles in blood circulation by facilitating the movement of blood through the vascular system. Cohesion, the attraction between similar molecules, helps maintain the integrity of the blood column, allowing it to flow smoothly through vessels. Adhesion, the attraction between different substances, enables blood to adhere to the walls of blood vessels, promoting efficient transfer of nutrients and gases. Together, these properties ensure effective circulation and oxygen delivery throughout the body.
how to make plant cell mole
yes
cohesion helps water and minerals flow because... water molecules cling to each other as a result of a force called cohesion cling to molecules of other substances, too , and this force is calledadhesion. This forces water to climb up tubes of xylem tissue.
