In a biological context, motility specifically refers to the ability of an organism or a cell to move independently and purposefully. This movement can occur through various mechanisms such as swimming, crawling, or other forms of locomotion. Motility is crucial for many functions in biology, including the movement of single-celled organisms to find food, evade predators, or migrate to suitable environments. It also plays a vital role in multicellular organisms, particularly in processes such as wound healing, immune response, and reproduction.

The other options describe different biological concepts. Healing quickly relates to the body's ability to repair itself, which is a distinct physiological process but does not involve movement. The absorption of nutrients pertains to how organisms take in substances necessary for growth and energy, primarily involving the digestive system rather than motility. Reproduction relates to the biological processes that lead to the production of new organisms or cells, which may involve motility in some species but is not defined by it. Thus, the emphasis on movement makes the choice of motility as the ability to move the accurate definition in this context.
