Detailed explanation-1: -The leaves of forest trees have adapted to cope with exceptionally high rainfall. Many tropical rainforest leaves have a drip tip. It is thought that these drip tips enable rain drops to run off quickly. Plants need to shed water to avoid growth of fungus and bacteria in the warm, wet tropical rainforest.

Detailed explanation-2: -The tropical rainforest biome has four main characteristics: very high annual rainfall, high average temperatures, nutrient-poor soil, and high levels of biodiversity (species richness). Rainfall: The word “rainforest” implies that these are the some of the world’s wettest ecosystems.

Detailed explanation-3: -Most are orchids, bromeliads, ferns, and Philodendron relatives. Tiny plants called epiphylls, mostly mosses, liverworts and lichens, live on the surface of leaves. Neoregelia sp. Bromeliads are found almost exclusively in the Americas.

Detailed explanation-4: -There is a lot of rain in the rainforest. Many plants have developed drip tip leaves to quickly funnel water off themselves to prevent rotting and fungus growth. These are thin, woody vines that plant their roots in the ground and then use trees as support to climb higher to reach the sunlight.

Detailed explanation-5: -Plant Adaptations in the Tropical Rainforest Biome The leaves on most of the plants have what is called drip tips which help plants shed the excess moisture from the rainfall. The trees have long, very straight trunks and don’t branch out until they reach the canopy where sun-light can be found.
