Adhesion involves attraction between which types of molecules?

Adhesion refers to the tendency of different types of molecules to attract and stick to each other. This process is essential in many biological and physical systems, such as water's ability to adhere to plant cells, which facilitates nutrient transport.

Unlike molecules, such as water molecules and the surfaces of solid objects, interact through various forces, including hydrogen bonding and van der Waals forces. This interaction allows different substances to combine or stick together, leading to phenomena such as capillary action.

The other options focus on interactions that do not accurately describe adhesion. The attraction between like molecules (options referring to them as similar or alike) generally describes cohesion instead, where identical molecules attract each other. Polar and non-polar interactions do not consistently result in adhesion due to their differing affinities, making the understanding of adhesion primarily relevant to unlike molecules.
