Vedclass · Answer

(C) The movement which occurs due to the difference in the rate of growth on two opposite sides of a plant organ is called nastic movement.When movement occurs due to faster growth of the upper surface of an organ compared to the lower surface,it is called epinasty.The opening of a flower is a classic example of epinastic movement,where the growth of the inner surface of the petals is faster than the outer surface,causing the flower to open.
