Chemotaxis

Chemotaxis is the movement of an organism or a cell in response to a chemical gradient. This biological phenomenon typically involves the movement towards higher concentrations of beneficial substances (such as nutrients) or away from harmful substances (such as toxins). Chemotaxis is observed in various organisms, including bacteria, single-celled organisms, and multicellular organisms, and is crucial for processes such as immune response, wound healing, and the navigation of cells to specific sites in tissues.
