Question
Which of the following movement is not related to auxin level ?
Options
A.Bending of shoot towards light
B.Movement of root towards soil
C.Nyctinastic leaf movements
D.Movement of sunflower head tracking the sun
Solution
Phototropic movements, eg, bending of shoot toward light, movement of sunflower head trking the sun, etc and geotropic movement, eg, movement of root towards soil are mediated through differential distribution of IAA.
Nyctinastic leaf movements are affected by diurnal variation of light intensity and temperature, such as elliptical up and down movement of the two lateral leaflet.
