How do auxins promote the growth of a tendril around a support? Describe in brief. (CCE 2012) -Biology-10

Description : How do auxins promote the growth of a tendril around a support? Describe in brief. (CCE 2012) -Biology-10

Last Answer : Auxin is plant hormone which is synthesized at the tip of the shoot. It helps the cell grow longer. When a tendril comes in contact with a support, auxin stimulates faster growth ... , indole acetaldehyde. Synthetic auxins: Napthalene acetic aicd, indole butyric acid, 2,4-dichorophenoxyacetic acid.

How do auxins promote the growth of a tendril around a support ? -Biology-10

Description : How do auxins promote the growth of a tendril around a support ? -Biology-10

Last Answer : 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 which is in contact with the support and makes the tendril twirl (or bend) around the support.
