Motility refers to the ability of an organism or a cell to move or exhibit self-propulsion. If an organism is motile, it can actively move itself or its parts. This movement may be achieved through the use of appendages, such as wings, limbs, or flagella, or through changes in shape or contraction of muscles.
On the other hand, a nonmotile organism is unable to move or has limited mobility. These organisms are typically fixed or immobile, meaning they are unable to change their location or move from one place to another. Nonmotile organisms may still have other means of survival, such as relying on external forces, such as wind or water currents, for dispersal or transportation.
