When ground water is drawn up into a tree trunk it is able to reach the upper leaves of the tree because of the special properties of water. Which of the following would be CORRECT about this setting? Adhesion is occurring. Cohesion is drawing the water toward the leaves. Hydrogen bonds between water molecules are playing a role. All of the above are correct.

All of the above are correct.

Explanation:

Cohesion is the force between like molecules that hold them together. It is responsible for the surface tension in water. It holds the hydrogen bonds together, giving rise to surface tension in water. Adhesion is the attraction between unlike molecules. The forces of adhesion and cohesion all assist to pull water up the xylem of plants to the leaves. Hence hydrogen bonding, adhesion and cohesion all work together as water is pulled towards the plant leaves.
