Question

what are the tendrils

Answer 1

Tendril, in botany, plant organ specialized to anchor and support vining stems. Tendrils may be modified leaves, leaflets, leaf tips, or leaf stipules; they may, however, be derived as modified stembranches (e.g., grapes). Other special plant structures fulfill a similar function, but the tendril is distinctive in being a specialized lateral organ strongly possessing a twining tendency causing it to encircle any object encountered.
