How do tendrils help in grape plant?
Grapevine (Vitis vinifera L., Vitaceae) belongs to the genus Vitis, and is characterized as a vine due to the presence of tendrils, which are located opposite to leaves. Tendrils are thigmo-responsive organs, able to carry out delicate mechanosensory responses upon touch and related stimuli.

Initially, tendrils develop water-secreting openings called hydathodes at their tips. Subsequently, the hydathodes degenerate and pressure-sensitive cells develop along the tendril. On contact with solid objects, these specialized cells activate elongation and cellular growth on the opposite side of the tendril.
