tendril

Examples of tendril in the following topics:

• Plant Responses to Wind and Touch

  • Tendrils are one example of this.
  • A tendril is a specialized stem, leaf, or petiole with a threadlike shape that is used by climbing plants for support.The meristematic region of tendrils is very touch sensitive; light touch will evoke a quick coiling response.
  • Application of jasmonic acid is sufficient to trigger tendril coiling without a mechanical stimulus.
  • Tendrils of a redvine produce auxin in response to touching a support stick and then transfer the auxin to non-touching cells.

• Stem Modifications

  • Tendrils are slender, twining strands that enable a plant (like the buckwheat vine) to seek support by climbing on other surfaces.
  • Found in southeastern United States, (a) buckwheat vine (Brunnichia ovata) is a weedy plant that climbs with the aid of tendrils.
