<P> Chemotaxis ( from chemo - + taxis ) is the movement of an organism in response to a chemical stimulus . Somatic cells , bacteria , and other single - cell or multicellular organisms direct their movements according to certain chemicals in their environment . This is important for bacteria to find food ( e.g. , glucose ) by swimming toward the highest concentration of food molecules , or to flee from poisons ( e.g. , phenol ) . In multicellular organisms , chemotaxis is critical to early development ( e.g. , movement of sperm towards the egg during fertilization ) and subsequent phases of development ( e.g. , migration of neurons or lymphocytes ) as well as in normal function . In addition , it has been recognized that mechanisms that allow chemotaxis in animals can be subverted during cancer metastasis . </P>
