There is debate about the purpose of "exfoliating bark" (the biological term).The most commonly accepted theory is that it's an evolutionary development which helps the tree shed lichens and parasites such as boring insects, which lay their eggs on the bark. Leaves are usually thick and have pointed "drip tips" to help rain roll off them. The plants in the arid of desert regions have modified leaves covered with hair or waxy coating and an extensive root system.

Pneumatophores are specialized root structures that grow out from the water surface and facilitate the aeration necessary for root respiration in hydrophytic trees such as many mangrove species (e.g., Avicennia germinans and Laguncularia raecemosa), bald cypresses, and cotton (tupelo) gum (Nyssa aquatica). The layers of rainforest are connected by vines and ferns, and mosses grow on the trees. This canopy lets as little as one percent of the sunlight reach the forest floor in some regions.

Rough, thick bark manages heat loss and moisture Hydrophytic trees often have more intercellular spaces in their tissues to promote aeration of their roots. Trees in the rainforest grow very tall because they have to compete with other plants for sunlight. Rainforests are Earth's oldest living ecosystems, with some surviving in their present form for at least 70 million years.
