Tendril

Specialisation of plant parts used to climb or bind

In botany, a tendril is a specialized stem, leaf or petiole with a thread-like shape used by climbing plants for support and attachment, as well as cellular invasion by parasitic plants such as Cuscuta. There are many plants that have tendrils; including sweet peas, passionflower, grapes and the Chilean glory-flower. Tendrils respond to touch and to chemical factors by curling, twining, or adhering to suitable structures or hosts.
