Showing movement or growth toward or in response to something, especially in biology when an organism turns toward a stimulus.
From Greek 'gamos' (marriage, union) and 'tropos' (turning), combining to mean 'turning toward.' The term evolved in botanical and biological contexts to describe directional growth responses.
Plants and fungi use gamotropic responses to find each other—it's like nature's dating app where roots literally grow toward beneficial partners! This biological 'attraction' has been happening for hundreds of millions of years.
