Question

Difference between trophic and nastic movement?

Answer 1

NASTIC MOVEMENT;- 
1]  non directional response  to stimulas..                                                              2]independent on growth on the plant                                                                3] change in turgor pressure  can induce change in movement ...           
 4] opening and closing of flower [ photosynthetic response]........                        5] nastic movement sare mostly found in specialized plants and organs.
 tropic movement;-
1] directional response to stimula ..
.2] depended on growth on the plant
 3] independent on change on turgor pressure
4] photo tropic response
5]Tropic movements are found virtually in all plants
