Name the property that causes tendril to circle around the object ?Explain how it happens and how is plant benefitted by it ?

The property of the plants that causes tendrils to circle around the support is called thingmotropism (response to touch or physical contact). When a tendril comes into contact with its support, the contact acts as a stimulus and as tendrils are positively thigmotropic, the side of the tendril which is opposite to the side of contact will grow at a faster rate than the contact side. The cells on the contact side will compress, which enhances the curving response. Therefore, the non-contact side begins to elongate faster than the rest of the tendril, while the contact side actually compresses. This causes the tendril to curve toward the site of contact and in this manner tendrils coil around a support. It helps plant to climb against the support.
