Solution
The correct option is D Moment of curvature
If the movement of curvature exhibited by plant organs is due to some external stimuli (caused by light, temperature, gravity, foreign bodies, etc), it is called induced movement of curvature. There are several spontaneous movements of curvature like Nastic movements, nutation, etc. Opening of sunflower is due to the light radiation of the sun. So it is an example of photonastic movement. Seismonasty is induced by movement by touch, shock, rain, wind, etc. Example: the leaves of plants Mimosa pudica and M.spegazzinii. All these are included in movement of curvature.
