Dear Pankaj, If the tendril belongs to *Ampelocissus *(for e.g.) then it will bear an inflorescence of several small flowers. Since the tendrils are very close to the flowers, I thought they may help in attracting insect pollinators by their fluorescence or UV light.
This is just an 'hypothesis'. It will be fine even if it is proved wrong... :) If it is proved right, then it will become a 'theory' (!).
