In tropical and temperate climate forests alike, light is essential for the survival of plants.
In tropical and temperate climate forests alike, light is essential for the survival of plants. While trees develop a self-supporting structure thanks to their trunks, allowing them to rise above others, a large number of species are able to climb up these same trees without having to make too much effort. These lianas, which are found all over the world in a large number of plant families, are the result of many different evolutions: coiled stems, modified leaves or even adventitious roots. They can use anything to climb up to the canopy.
