In botany, a tendril is a specialized stem, leaf or petiole with a thread-like shape used by climbing plants for support and attachment, as well as cellular invasion by parasitic plants such as Cuscuta. [1]

Stem tendrils are branch modifications that help the plant to climb. Leaf tendrils are leaf or leaflet modifications that emerge from leaf nodes and usually support the stem. Slender and spirally coiled tendrils develop from the auxiliary bud.

What Are Stem Tendrils? A Biological Masterpiece. Stem tendrils are specialized, elongated structures derived from the stem or its components, designed to assist climbing plants in their quest for sunlight. Typically green and leafless, these thread-like adaptations are both flexible and strong, allowing plants to latch onto supports such as trees, fences, or other vegetation.

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 stem branches (e.g., grapes).

Stem tendrils: Stem or its branches get modified into green thread like leafless structures called tendrils which are meant for climbing. These may be branched or un-branched.

What is Stem Tendril? When stems are modified into threadlike leafless structure then they are known as stem tendril. Their major role is for climbing purposes, they don't necessarily contain a branch. Further Stem Tendril is classified into different types. They are as follows: Axillary: E.g., Passiflora . Extra-Axillary: E.g., Luffa

2024年3月20日 · The stem tendril helps the plants to climb surfaces whereas the leaf tendril helps the plant to attach and anchor itself to surfaces. Both these structures are modifications of plant parts that help in plant growth and development.

2024年12月13日 · Tendrils are modified flower clusters. In botany, a tendril is a specialised stem, leaf, or petiole that is threadlike in shape and used by climbing plants for support and attachment. Tendrils are also used by parasitic plants such as Cuscuta for cellular invasion.

Stems (or entire shoots) of some species deviate in structure and function from a typical stem. These are called stem modifications (shoot modifications). While leaves are part of the shoot, modifications involving just the leaf are discussed separately (see Leaf Modifications).

The main difference between stem tendrils and leaf tendrils is that Stem tendrils are derived from a particular part of a stem whereas leaf tendrils are derived from a whole leaf or a particular part of a leaf. Some stem tendrils develop from the axillary bud, and some develop from the apical bud
