chemotaxis

This term describes a precise biological mechanism where cells or organisms navigate their environment based on chemical gradients. It is a technical term used primarily in microbiology, biochemistry, and cell biology to explain how bacteria find nutrients or how immune cells locate sites of infection.

As a mass noun representing a biological process, it is treated as uncountable. It does not have a plural form in standard scientific usage; instead, researchers refer to different types of chemotaxis or specific instances of the process.
