Why does a vining plant such as a morning glory instinctly know to go towards something that it can climb on??

Vines climb using Tendrils by twining or by clinging.


Most vines in the Southern Hemisphere will twine counter-clockwise and in the Northern the opposite as observed by


Charles Darwin earlier discoveries.





The scientific reason why vines know to grow towards something


is explained below on the second link. It is not fully conclusive


but I do know that they instinctively grow towards a host whether


that be a fence or other plant etc and will attach by the use of


tendrils and grow towards a light source to expose a greater


surface area of there leaves and towards the free air.


Some scientists also believe that vines grow in response to threats as do some plants that have thorns to protect their fruits being eaten by animals.





Many scientists agree including 'Darwin' that it's as if these vines


have a mind of their own and will do as they will.

Vining plants have "feelers or tendralls" (my own terminology) that grab onto other plants or structures ie; trellaises etc... Without going on-line to look up exactly "why", I can't answer that, sorry.

Reply:they don't, they find it. Having watched videos of them growing in school they actually sprout up and grow out and in a circle trying to find something to climb on
