Cohesion-Adhesion Theory
Network integrity depends on both internal cohesion (units working together) and external adhesion (connection to infrastructure).
Cohesion: Hydrogen bonds between water molecules create tensile strength of approximately 30 megapascals - strong enough to withstand the pulling force even at 60+ feet height. Adhesion: Water molecules bond to the xylem cell walls (hydrogen bonding to cellulose), preventing the column from breaking away from the vessel surfaces. Together, cohesion and adhesion create a continuous water thread from soil to leaf. Pull the top, and the entire column rises.
Business Application of Cohesion-Adhesion Theory
Network integrity depends on both internal cohesion (units working together) and external adhesion (connection to infrastructure). Both forces must be present for system to function under stress.
