Nyctinastic leaf movement

Vedclass · Answer

(A) Nyctinastic or sleep movements are primarily caused by changes in turgor pressure within the pulvinus cells,which is triggered by the alternation of day and night. These movements are independent of auxin concentration. In contrast,the movement of roots towards soil (geotropism),the movement of shoots towards light (phototropism),and the tracking of the sun by sunflowers (heliotropism) are all growth-related movements mediated by the differential distribution of auxin.

Which of the following movements in plants is not related to a change in auxin level?
