This type of tundra reaches its greatest development on the northern Alaskan coastal plain. This long separation has impeded the establishment and development of land-based flora and fauna in the Antarctic. Deserts experience extreme shortages of water due to lack of precipitation. The average temperature in the Arctic regions is -18 degrees F. It gets much colder in the winter and is warmer in the short summers. These two articles discuss findings related to Arctic plant mobility and resiliency. Circulation of air masses around the Earth transports industrial pollutants from temperate regions into the Arctic and Antarctic. At such times, the desert sands become covered in colourful daisies, as the plants race to produce flowers and form seeds before the moisture dries. The nursery is a worker-owned small business . Alexander Supan found good coincidence between the tree line and the 50 F (10 C) July isotherm, a figure later modified by Otto Nordenskjld to allow for spring temperatures. Polar environments are in the Arctic and Antarctic regions. A desert biome is a collection of habitats that that develop in arid (dry) environments as a result of little rainfall (50cms per year) or no rainfall at all. They receive very little precipitation, the main forms of which are snow and fog. By contrast, in northern Europe and Siberia the tree line is formed by larch, pine, and fir.

Nights can last for weeks when the sun barely rises during some months in the winter, and the temperature can drop to -94 F (-70 C). Two main vegetation zones are found in the polar lands. This limit generally coincides with the isoline of annual net solar radiation of 75 to 80 kilojoules per square centimetre, which closely parallels the 10 C (50 F) July isotherm. Polar air is very dry and produces little or no rain. Depending on its geographical location, the annual precipitation in a desert varies from half an inch to as much as 15 inches. The old man cactus is a large plant with multiple cylindrical thorny stems forming a large shrub. Polar deserts are characterized by extremely low temperatures and arid conditions.

Desert plants may have to go without fresh water for years at a time. Small plants and shallow root systems compensate for the thin layer of soil, and small leaves minimize the amount of water lost through the leaf surface. Its low growth and spreading nature make it ideal for ground cover in full sun or planting along paths, beds, and borders. Mushrooms are a well-known example of fruiting bodies. The ball of light dry weed is the whole plant when it detaches from the root system. The cactus blooms with bright red-orange flowers, creating an attractive crowning ring. The main characteristic of deserts is a shortage (or complete lack of) precipitation; some desert regions go for years on end without rain. This type of vegetation is common in all circumpolar lands close to the tree line and is conspicuous in the inner fjords of southwestern Greenland and in northern Iceland. Although summers are brief at high latitudes, the days of summer are long. A study of plants aligns with the Life Science content standards of the National Science Education Standards. This species has no tadpole stage but develops from an egg directly into an adult an adaptation to its arid environment.

Other significant factors that have hampered terrestrial biotic evolution are the harsh climate, the ice cover that completely engulfed the continent during the Pleistocene glaciations, and the present limited number of ice-free land areas, which are restricted primarily to the coastal fringes and nunataks (mountain peaks surrounded by the ice cap). After flowering, cactus fruits appear and persist on the desert plant for several months. The desert biome consists of species able to live in these inhospitable conditions. Rodents, in turn, are preyed upon by predators such as snakes, foxes, bobcats and owls that also live in deserts. Net photosynthesis (net carbon uptake) continues to be positive during drought until the leaf water stress declines to the range of -21 to -29 bars, which is considerably below the . Polar deserts have very poor rocky soil with few plants and a lower biodiversity than other . Many of Earths coldest deserts are found in the Arctic or Antarctic regions of the planet. Wright Valley, one of the McMurdo Dry Valleys in Antarctica, where extremophile cyanobacteria, called hypoliths, live. Flowers of some plants are cup-shaped and direct the sun's rays toward the center of the flower.

Desert marigolds are flowering perennial plants found in the deserts of Mexico, Utah, California, and Arizona. During dry seasons, the bushy plant loses its leaves and relies on moisture stored in its stems to survive hot desert climates. A plant's performance is governed by the total climate: length of growing season, timing and amount of rainfall, winter lows, summer highs, wind, and humidity. Its attractive shape gives the plant tremendous visual appeal in desert gardens or xeric landscapes. The High Arctic is distinguished from the Low Arctic based on ecological criteria, which include a shorter growing season, cooler summers, and a marked reduction in species of flora and fauna.

The bare rock surfaces support thin brown, black, or gray crustaceous lichens that swell and become soft when wet; some of the larger black lichens are edible and are generally known as rock tripe. In the past these lichens have been used for food by starving explorers. The species vary but typical are those in the western American Arctic, which include the blue-spiked lupine, wild crocus, mountain avens, arctic poppy, and saxifrage. The air is dry in deserts, and clouds do not form; therefore, clear skies are also a characteristic of deserts. The stems have thin linear leaves up to 4 (10 cm) long.
