Question

DIFFERENCE BETWEEN AUTONOMIC AND PARATONIC PLANT MOVEMENT



DIFFERENCE BETWEEN NASTIC AND TROPIC MOVEMENT

Answer 1

In tropic movements, there is directional growth of a plant, or part of a plant, in response to an external stimulus such as gravity or light. So the direction of the stimulus controls the orientation of growth. The direction of a nastic movement is independent of where the signal comes from.
