aerial root

botany
Also known as: prop root

Quick Summary

An aerial root is any root that is exposed to the air. These roots are commonly found in epiphytes and climbers, where they anchor the plant to its support and can sometimes aid in photosynthesis. Aerial roots are a type of adventitious root, meaning they grow from a part of the plant other than the main root system, such as from stems or leaves.12

Examples of plants with aerial roots include corn, screw pines, and banyan trees, which use them for support. In tropical rainforests, epiphytic plants like orchids and Tillandsia species rely on aerial roots for attachment to other plants or rocks. Some climbing plants, like English ivy, also use specialized aerial roots to grip surfaces.2
