There is no overall charge to a water molecule, but there is a slight positive charge on each hydrogen atom and a slight negative charge on the oxygen atom. The charged particles will form hydrogen bonds with a surrounding layer of water molecules. Cohesion exists because of the polarity of water. This is also why water forms droplets when placed on a dry surface rather than being flattened out by gravity. For instance, cohesion causes water to form drops and adhesion keeps the water drops on the surfaces of leaves and flowers in place. What is adhesion and give an example? C. Decomposers break down waste and return nutrients to the environment. Why is adhesion Why is water cohesion and adhesion important to life? Capillary action is vital for plant life and is the result of adhesion and cohesion. The adhesion of water to vessels inside a plant allows water to travel throughout a plant. Cohesion holds the water together so all of the liquid is dragged upward into the plant against gravity. Cohesive and adhesive forces are important for the transport of This pull results from the tendency of water molecules being evaporated on the surface of the plant to stay connected to water molecules below them, and so they are pulled along.
