WebFeb 27, 2024 · Adhesion describes how well liquid molecules stick to surfaces. Water molecules stick to glass and plastic surfaces. In contrast, mercury atoms stick well to each other, but are not as attracted to a container surface. Surface tension is the tension on a liquid at its interface with air that minimizes the liquid surface area. WebCell adhesion is a crucial function in the formation of tissues, organs, the body, and to display high-order functions of living organisms. Almost all cell adhesions are mediated by cell surface molecules, called receptors, and direct observations and quantifications of these receptors are fundamental to understanding the cell adhesion phenomena.
