In botany, a tendril is a specialized stem, leaf or petiole with a threadlike shape that is used by climbing plants for support, attachment and cellular invasion by parasitic plants, generally by twining around suitable hosts. They do not have a lamina or blade, but they can photosynthesize. They can be formed from modified shoots, modified leaves, or auxiliary branches and are sensitive to airborne chemicals, often determining the direction of growth, as in species of Cuscuta.

Tendrils are specialized structures found in certain plants and fungi that are used for climbing, grasping, and anchoring. They are typically slender, spiraled, or curling in shape and help the plant reach out for support or resources nearby. Tendrils often respond to touch or contact stimuli, allowing the plant to coil around a support structure for stability and growth.
Tendrils work by a process known as thigmotropism. When the tendril touches something solid, it begins to wrap around the object and thus works by holding the plant in place.
Leaf tendrils originate either from stipules or leaflets whereas the stem tendrils are modification of axillary buds representing the stem branches.
No, pea plants are an example of vines that use leaf tendrils for support, not stem tendrils. Stem tendrils are specialized structures that aid climbing plants in attaching to structures for support. Pea plants have leaflet tendrils that wrap around supporting structures to help the plant climb.
Yes, grapevines are related to stem tendrils because grapevines use their tendrils, which are modified stem structures, to support themselves by wrapping around structures like trellises or other plants. Tendrils are specialized plant structures that help vines climb and support themselves.
Thigmotropism - tendrils of climbers exhibit a positive thigmotropism by growing towards and wrapping around a support structure to aid in climbing and anchoring the plant.
They are the plant's tendrils.
