chemotaxis

A response of motile cells or organisms in which the direction of movement is affected by the gradient of a diffusible substance. Differs from chemokinesis in that the gradient alters probability of motion in one direction only, rather than rate or frequency of random motion.

Chemotaxis

Movement of a cell in response to a chemical; movement may be toward an attractant chemical or away from a repellent chemical.

Chemotaxis

the movement of cells in response to chemical messengers. The movement of neutrophils and macrophages into damaged tissues is brought about by signals released by damaged tissues, and bacterial products.. The term applies to the movement of any organism attracted by a specific chemical, which may be a suitable nutrient.
