Aerial roots are the above-ground roots that extend from the base of a plant and hang in the air. They are commonly found in plants that grow in tropical and humid climates. There are several synonyms for the term "aerial root," including air root, dangling root, epiphytic root, and adventitious root. Air root refers to the roots that grow above the ground, while a dangling root describes its hanging appearance. An epiphytic root refers to a type of aerial root that attaches itself to other plants. Lastly, an adventitious root refers to any root that grows from an unexpected or unusual location on a plant, such as from a stem or leaf.
