<P> According to cohesion - tension theory , water transport in xylem relies upon the cohesion of water molecules to each other and adhesion to the vessel 's wall via hydrogen bonding combined with the high water pressure of the plant 's substrate and low pressure of the extreme tissues ( usually leaves ) . </P>
