Answer 1

Lianas are climbing woody vines that drape rainforest trees. They have adapted to life in the rainforest by having their roots in the ground and climbing high into the tree canopy to reach available sunlight. Many lianas start life in the rainforest canopy and send roots down to the ground.
Lianas adaptations include stem twining, clasping tendrils arising from stem, leaf and branch modifications, thorns and spikes that attach the liana to its host, downward-pointing adhesive hairs, and adhesive, adventitious roots . . .
