The part of the tendril in contact with the support doesn't grow as fast as the other part of plants, it coils around the support with the help of plant hormone called Auxin. This causes the tendril to coil around the support. The unequal growth is due to more secretion of auxin in the other end and less secretion in the end in contact with the support.
