Tendrilsthat is a botanical term referring to the specialized plant organs that enable climbing plants to attach themselves to surfaces and provide support. These structures are typically thin, wiry, and flexible, allowing them to coil around and grasp objects such as stems, branches, or man-made structures. The mechanism of attachment often involves thigmotropism, a directional growth response to touch. When a tendril encounters a suitable surface, it will begin to coil around it, tightening its grip over time.

Tendrils can develop from various plant parts, including modified leaves, stems, or even flower parts. For instance, in peas, tendrils are modified leaves, while in grapevines, they are modified stems. The morphology and function of tendrils can vary significantly between species, reflecting different evolutionary adaptations to their environments and climbing strategies. Some tendrils are sensitive to light and may exhibit phototropism in addition to thigmotropism.

The primary role of tendrils is to provide the climbing plant with an advantage by allowing it to reach sunlight more effectively and escape competition from lower-growing plants. This improved access to light is crucial for photosynthesis and overall plant survival. Additionally, the support provided by tendrils can help protect the plant from physical damage and improve its reproductive success by elevating flowers and fruits. The presence and type of tendrils are often key characteristics used in plant identification and classification.
