What is cohesion and adhesion?
Consider water – the individual molecules “stick” to each other by hydrogen bonds – this is the cohesive property of water – it holds together. Adhesion is when something sticks to something else (like adhesive tape, glue, etc). Water has an affinity, for example, with the walls of xylem tubes and this adhesion helps move water up the plant. Both adhesion and cohesion help in the transport of water in plants.
