Most tundra flowering plants evolved to adapt to the severe cold in the region by growing hair in their leaves and stems. Animal adaptation to the tundra climage - BBC Bitesize because of the cool weather even in the summertime. The tundra, Earths coldest biome, is home to some impressively resourceful plants. Shrubs also prevent snow from reflecting heat from sunlight back into space, which can warm the Earths surface further. (The word tundra derives from the Finnish word tunturia, meaning barren or treeless hill.)

Pinyon pines have vertical and horizontal root systems that reach out 40 feet in both directions to provide water. Short plants can better avoid In many areas, there can be a buildup of organic matter over time in areas where the ground freezes. For more info, see, https://askabiologist.asu.edu/plants-tundra, Public Service and These microbial communities are active under the snow, and their composition changes dramatically from winter and spring to summer in response to changes in soil temperature, moisture, carbon availability, and the nature of carbon-containing substrates (the surfaces upon which microbes live). Bearberry plants grow on rocks (which help them stay out of the wind) and sand. Biomes are areas of similar climate and temperature that have distinctive plants and animals that have adapted to the conditions of the region. It is known for its beautiful purple flowers. On rocky slopes and peaks, plants are found in scattered patches where there is a bit of soil and some snow cover in winter. Rains in the tundra are rare, almost like a desert.

Scientists use them as bioindicators of the quality of the air. The tundra is a treeless biome in which low temperatures and short growing seasons limit plant growth above a certain height. Animals in the tundra are also adapted to extreme conditions, and they take advantage of the temporary explosion of plant and insect life in the short growing season. For example, behavioral adaptations include going dormant during unbearable heat or equally difficult conditions and returning later. Tundra wildlife includes small mammalssuch as Norway lemmings (Lemmus lemmus), arctic hares (Lepis arcticus), and arctic ground squirrels (Spermophilus parryii)and large mammals, such as caribou (Rangifer tarandus). Like other mosses, arctic moss has tiny rootlets instead of traditional roots, only they have found interesting ways to adapt to their exceptionally cold climate.
