No plants live on a glacier. While plants can be found in a variety of extreme environments such as deserts, rainforests, and mountains, glaciers are not hospitable ecosystems for plant growth. Glaciers are characterized by cold temperatures, strong winds, continuous ice and snow cover, and unstable surfaces that make it difficult for plants to establish roots. Additionally, the melting water on glaciers often lacks essential nutrients necessary for plant growth.

Instead, glaciers may have various microbial life forms that can survive the extreme conditions. These can include bacteria, algae, and fungi that colonize the underside or inside of the ice, often forming unique ecological communities adapted to the cold environment.
