Tendril
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.
History
The earliest and most comprehensive study of tendrils was Charles Darwin's monograph On the Movements and Habits of Climbing Plants, which was originally published in 1865. This work also coined the term circumnutation to describe the motion of growing stems and tendrils seeking supports. Darwin also observed the phenomenon now known as tendril perversion, in which tendrils adopt the shape of two sections of counter-twisted helices with a transition in the middle.
Biology of tendrils
In the garden pea, it is only the terminal leaflets that are modified to become tendrils. In other plants such as the yellow vetch (Lathyrus aphaca), the whole leaf is modified to become tendrils while the stipules become enlarged and carry out photosynthesis. Still others use the rachis of a compound leaf as a tendril, such as members of the genus Clematis.

Tenderly
by: Frank SinatraThe evening breeze caressed the trees tenderly,
The trembling trees embraced the breeze tenderly.
Then you and I came wandering by,
And lost in a sigh were we.
The shore was kissed by sea and mist tenderly;
I can't forget how two hearts met breathlessly.
Your arms opened wide and closed me inside;
You took my lips, you took my love so tenderly.
(Instrumental)
The shore was kissed by sea and mist tenderly;
I can't forget how two hearts met breathlessly.
Your arms opened wide and closed me inside;
