Positive chemotaxis, also known as chemotropism, is a biological process where cells move in response to a chemical stimulus. Synonyms for this term include chemotactic response, directed migration, and chemotactic behavior. Chemotactic response is a term used to describe the directional movement of cells towards a chemical source. Directed migration refers to the movement of cells in a specific direction, guided by a chemical signal. Chemotactic behavior is a more general term that encompasses both directed migration and chemotactic response. These synonyms are often used interchangeably to describe the ability of cells to sense and respond to chemical signals in their environment, which is critical for many biological processes such as wound healing and immune responses.
