Question

Distinguish between tropic movements and nastic movements in plants. Give examples to illustrate your answer.

Answer 1

Explanation:

Nastic movements are different than the tropic movements because tropic responses depend on the stimulus direction, whereas nastic movement direction is independent of the position of stimulus. A tropic movement is generally a growth movement but a nastic movement may or may not be related to a growing movement

Example: Movement of shoot towards the sunlight (phototropic movement). Drooping of the leaves of Mimosa pudica due to touch (Thigmonastic movement)
