Tendril
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 found by touch. They have a strong evolutionary pressure to maximize contact with objects to support the plant's growth. This can be seen in their ability to grow in the direction of a support and their subsequent formation of adhesive pads.
Function
Tendrils serve two primary functions for plants. First, they support the plant and help it to grow in the direction of light, which is essential for photosynthesis. Second, they help the plant to attach itself to other plants or structures, which can provide additional support and stability.
Structure
Tendrils are typically slender and threadlike, and are often spirally coiled. They can be found in a variety of plants, including vines, some types of ferns, and other climbing plants. The structure of tendrils can vary depending on the type of plant. For example, in some plants, tendrils are modified leaves or leaf parts, while in others, they are modified stems or stem parts.
Mechanism of Coiling
The mechanism of coiling in tendrils is a subject of ongoing scientific study. It is known that the coiling begins with the tendril reaching out from the plant in a straight form. When the tendril contacts a support, it wraps around the object and begins to coil. This coiling action pulls the plant closer to the support, helping it to climb.
Evolution
The evolution of tendrils is also a topic of scientific interest. It is believed that tendrils have evolved independently in multiple plant lineages. The evolution of tendrils is often associated with the evolution of climbing habit in plants.
