Adhesion and Cohesion of Water

Cohesion: Water is attracted to water
Adhesion: Water is attracted to other substances

Adhesion and cohesion are water properties that affect every water molecule on earth and also the interaction of water molecules with molecules of other substances. Essentially, cohesion and adhesion are the "stickiness" that water molecules have for each other and for other substances. The water drop is composed of water molecules that like to stick together, an example of the property of cohesion. The water drop is stuck to the plant stems, which is an example of the property of adhesion.
