A sleep movement in plants is a nastic response, that occurs daily in response to :
1 dark
2 light
3 water
4 both a and b
Explanation:
D A sleep movement in plants is a nastic response, that occurs daily in response to dark and light. In this case, plant close up their leaves and petals in response to the onset of darkness because it is a rather fast response. It does not involve differential growth but changes in cellular turgor. Nastic movement is the movement of a plant part in response to an external stimulus in which the direction of reaction is not dictated by the stimulus direction. Thigmonasty Movement of a part of plants in response to touch eg. Mimosa pudica, folds leaves and droops when touched. It is also known as Seismonasty
