what are the tropic movements

Asked by  | 23rd Jun, 2008, 03:44: PM

Expert Answer:

A tropism  is a biological phenomenon, indicating growth or turning movement of a biological organism, usually a plant, in response to an environmental stimulus. In tropisms, this response is dependent on the direction of the stimulus (as opposed to nastic movements which are non-directional responses).
