Question

Different between tropic and nasic moment ​

Answer 1

Answer:

Tropic movements are paratonic movements of growth. Nastic movements are paratonic movements of variations. Example: Movement of shoot towards the sunlight (phototropic movement). Drooping of the leaves of Mimosa pudica due to touch (Thigmonastic movement).

Answer 2

Nastic movements differ from tropic movements in that the direction of tropic responses depends on the direction of the stimulus, whereas the direction of nastic movements is independent of the stimulus's position. The tropic movement is growth movement but nastic movement may or may not be growth movement.
