Detailed explanation-1: -In the xylem vessels, water molecules are strongly attracted to each other and exhibit a “stickiness” called cohesion that is due to the formation of hydrogen bonds between different water molecules. The “stickiness” between water molecules and the xylem vessel walls is called adhesion.
Detailed explanation-2: -Adhesion, which is molecular attraction between “unlike” molecules. In the case of xylem, adhesion occurs between water molecules and the molecules of the xylem cell walls. Cohesion, which is molecular attraction between “like” molecules. In water, cohesion occurs due to hydrogen bonding between water molecules.
Detailed explanation-3: -Cohesion and adhesion are two water properties that describe how water molecules interact with each other. and how water molecules interact with other things like leaves or even you. Cohesion means that water likes to stick to itself. and adhesion means that water likes to stick to other things.
Detailed explanation-4: -Water molecules are polar and can form a type of intermolecular association called a hydrogen bond. This cohesive property causes water molecules to be dragged up the xylem towards the leaves in a continuous stream.
Detailed explanation-5: -Water from the roots is ultimately pulled up by this tension. Negative water potential draws water from the soil into the root hairs, then into the root xylem. Cohesion and adhesion draw water up the xylem.
