Adhesion allows for water to move against gravity through plant cells. Cohesion may refer to: Cohesion (chemistry), the intermolecular attraction between like-molecules. For plants, adhesion allows for the water to stick to the organic tissues of plants. Why are cohesive and adhesive forces important for life? Cohesion allows for the development of surface tension, the capacity of a substance to withstand being ruptured when placed under tension or stress. These forces create a pull on the water column. Water is a polar molecule, meaning its charge is unevenly distributed with a delta negative oxygen and 2 delta positive hydrogens. Cohesion: Cohesion is an intermolecular attraction.
