Auxins are growth regulators of the plant. Plant produce auxin at the tip of bud.
A tendril is a specialised stem which supports a plant in climbing.
Auxin produced at tendril diffuses away from the contact point of the tendril.
Auxin elongates the cell.
As a result, there is uneven growth in the cells of the tendril. It results in curling of tendril to the support.
