) supports the plant. Tendrils are modified stems, leaves, or leaf parts or roots. Most young tendrils revolve slowly in their natural growth, as do the growing tips of roots and shoots; the tendrils of different plant varieties may have a consistent tendency to clockwise or to counterclockwise spiraling. The most common kind of tendril (pea, grape) coils around a slender support and then contracts spirally, becoming springy and drawing the plant to the support. The disk-tipped tendril (Virginia creeper, Boston ivy) adheres firmly to brick, stone, or wood, after which it too contracts. For other means of climbing in plants, see climbing plantclimbing plant,
any plant that in growing to its full height requires some support. Climbing plants may clamber over a support (climbing rose), twine up a slender support (hop, honeysuckle), or grasp the support by special processes such as adventitious aerial roots (English

Tendril

 

a usually filamentous organ characteristic of climbing plants that serves to attach the plants to other plants or to objects. Tendrils are the result of metamorphosis of shoots, leaves or parts of leaves, branches, inflorescences, or aerial roots. They wrap themselves around objects and twist spirally (haptotropism); sometimes special disklike suckers develop on the ends of tendrils. Tendrils are common in lianas, including grapes and cucurbits.
