Examples of cohesion in the following topics:

  • Water’s Cohesive and Adhesive Properties

    • This water can stay above the glass because of the property of cohesion.
    • Cohesion and surface tension keep the hydrogen bonds of water molecules intact and support the item floating on the top.
    • Why are cohesive and adhesive forces important for life?
    • Cohesive and adhesive forces are important for the transport of water from the roots to the leaves in plants.
    • Water's cohesive and adhesive properties allow this water strider (Gerris sp.) to stay afloat.

  • Movement of Water and Minerals in the Xylem

    • At night, when stomata close and transpiration stops, the water is held in the stem and leaf by the cohesion of water molecules to each other as well as the adhesion of water to the cell walls of the xylem vessels and tracheids.
    • This is called the cohesion–tension theory of sap ascent.
    • The cohesion-tension theory explains how water moves up through the xylem.
    • The cohesion–tension theory of sap ascent is shown.
