Plant Adaptations

Epiphytes

An epiphyte is a plant that grows on a different plant, and are often called "air plants." According to research gathered by an undergraduate research honors project from the Grand Valley State University, this adaptation allows these plants to reach sunlight easier and overcome the limited nutrients and water from the tropical rainforest soil. Their research also found that vascular epiphytes are an adaptation that is prevalent in most tropical rainforests, and make up about 1/2 of the world's flora and almost 1/4 of all vascular plant species in tropical biomes.

Drip Tips

A large part of the tropical rainforest climate is high levels of rainfall. Plants have adapted their leaves to withstand the rainfall, creating drip tips that let the water easily run off leaves. Based on a study conducted by the National Library of Medicine, drip tips are a long and narrow extension on a leaf, and are used to alleviate the harm of leaf wetting on the functionality of plants. Their data showed that drip tips are not formed in response to increases in precipitation, but primarily due to other factors such as temperature. Regardless of the cause, drip tips allow plant species of the tropical rainforest to resist the potential damage of heavy rainfall.

This graph was created by the Michigan Technological University and the International Association of Bryologists, and shows the ground-to-canopy gradiation in a lowland forest of the Amazon tropical rainforest. The data shows the prevalence of epiphytes in the tropical rainforest biome, as these epiphytes have adapted to grow closer to the sunlight that is blocked by canopies.

According to the digital library of JSTOR, the adaptation of drip tips (shown in the image above) are beneficial to plants of the tropical rainforest.
