Usage notes

(biology): Distinguished from taxis in that in a taxis, the organism has motility and moves towards or away from stimulus (e.g., bacteria, animals), while in a tropism the organism is not motile, and simply turns or grows towards or away from stimulus (e.g., plants, fungi). Similarly, kinesis is distinguished as non-directional movement.

In compound terms, analyzed as suffix -tropism, not stand-alone tropism.
