Popular flowering desert plants and shrubs are the desert lily, California poppy, and aloe vera plants. Ultraviolet radiation, previously intercepted by the ozone layer, is detrimental to most life because it inhibits photosynthesis and increases mutation rates in DNA and damages epidermal tissues in plants and animals. Permanently frozen areas on Earth can preserve organisms for tens of thousands of years. This flowering perennial has lush mounds of dark green lacy foliage surrounded by open, cup-shaped orange flowers. Nevertheless, near sea level where soil formation has been possible, a unique Antarctic tundra vegetation has developed, dominated by tussock-forming grasses and mosses. Icarus 224(2).
