WebPulling xylem sap: Transpiration Cohesion- tension mechanism or transpiration pull: Stomata are the sites of exchange of C0 2 and 0 2 between photosynthetic tissues and atmosphere. They are also sites of transpiration. The air in these stomata is saturated with water vapour since it is in contact with the most walls of the mesophyll cells. WebCohesive forces are responsible for surface tension, a phenomenon that results in the tendency of a liquid’s surface to resist rupture when placed under tension or stress. Water molecules at the surface (at the water-air interface) will form hydrogen bonds with …
