GENERAL HISTOLOGY

Detailed explanation-1: -Cohesion between the water molecules in the xylem vessel is complemented by the adhesion of water to xylem walls. The stickiness of the hydrogen bonds in water also helps it stick, or adhere, very tightly to the cell walls of xylem vessels. This property of water is called adhesion.

Detailed explanation-2: -Water molecules are bent so the hydrogen atoms are to one side of the oxygen atom. and when it come to molecules opposites attract. A bond forms between the negative side of one water molecule and the positive side of another. At that is what gives water its stickiness.

Detailed explanation-3: -Adhesion refers to the tendency of water molecules to be attracted, or ‘’stick”, to other substances. This is a result of the covalent bond between the two hydrogen atoms and the one oxygen atom in the water molecule.
