will come in contact with a support system (physical structure for the tendril to coil around). In a 2019 study done by Guerra et al., it was shown that without a support stimulus, in this case a stake in the ground, the tendrils will circumnutate towards a light stimulus. After many attempts to reach a support structure, the tendril will eventually fall to the ground. However, it was found that when a support stimulus is present, the tendril’s circumnutation oscillation occurs in the direction of the support stimulus. Therefore, it was concluded that tendrils are able to change the direction of their circumnutation based on the presence of a support stimulus. The process of circumnutation in plants is not unique to tendril plants, as almost all plant species show circumnutation behaviors.

199:, tendrils are often shown in angiosperms and little in fern. Based on their molecular basis of tendril development, studies showed that tendrils helical growth performance is not correlated with ontogenetic origin, instead, there are multiple ontogenetic origins. 17 types of tendrils have been identified by their ontogenetic origins and growth pattern, and each type of tendril can be involved more than once within angiosperms. Common fruits and vegetables that have tendrils includes

Self-discrimination may confer an evolutionary advantage for climbing plants to avoid coiling around conspecific plants. This is because neighboring climbing plants do not provide as stable of structures to coil around when compared to more rigid nearby plants. Furthermore, by being able to recognize

The mechanism of tendril coiling begins with circumnutation of the tendril in which it is moving and growing in a circular oscillatory pattern around its axis. Circumnutation is often defined as the first main movement of the tendril, and it serves the purpose of increasing the chance that the plant

plants form on the end of tendrils. The tendrils of aerial pitchers are usually coiled in the middle. If the tendril comes into contact with an object for long enough it will usually curl around it, forming a strong anchor point for the pitcher. In this way, the tendrils help to support the growing
