Question

why do tendrils always tend to grow around a support.?

Answer 1

Hyyy...
Here is ur answer....

The tendrils are sensitive to touch. When they come in contact with any support, the part of the tendril in contact with the object does not grow rapidly as the part of the tendril away from the object. This causes the tendril to circle around the object and thus cling to it .

Answer 2

When the tip of a tendril touches a support , then the auxins present in its tip move to that side of tip which is away from the support . Auxins promote growth . So due to more auxins in it , the side of tendril away from the support grows faster than the side which is in contact with the support and makes the tendril twirl around the support .
