Question

How do auxins promote the growth of a tendril around a support 0?

Answer 1

Answer:

auxins are phyto-hormones responsible for division pf plant tissue and responsible for both vertical and horizontal growth of a plant.

when a tendril is growing around a support and receives sunlight, auxins transfer to the shadier side and cause greater cell division to that side.

This causes growth of the plant towards the source of the light.

Hope you will be able to understand.
