Lianas are vascular plants rooted in the ground and maintain erectness of their stem by making use of other trees for support. They do not maintain direct physiological relation with those trees. Discuss the type of association the lianas have with the trees.

(N/A) The association between lianas and the trees they use for support is known as $Commensalism$.
In this type of interaction,one species benefits while the other remains unaffected.
Lianas benefit by gaining structural support to reach sunlight,which is essential for their growth and photosynthesis.
The host trees are neither harmed nor benefited by the presence of the lianas,as the lianas do not derive nutrients or water from the host trees.
