Deschampsia antarctica, the Antarctic hair grass, is one of two flowering plants native to Antarctica, the other being Colobanthus quitensis (Antarctic pearlwort). Photo Jason Hollinger. One adaptation of seaweed is that some types of seaweed, such as kelp, have holdfasts instead of roots. Currently, 4 general distributional patterns of lichens are known. The harsh Antarctic environment includes extreme conditions such as frequent darkness, minimal nutrients and running water, extremely high radiation in the summer and constant freezing temperatures during the winter. This "extreme plant" has therefore evolved in a number of ways in order to better adapt to its environment. Lichens can be found growing in most areas of the Antarctic that capable of supporting plant life. Hair Grass’s Scientific name is Deschampsia Antarctica. However when most normal grass will start forming big cold ice crystals, the Antarctic Hair grass only let small ice crystals stay on … Antarctic pearlwort (Colobanthus quitensis) is one of only two flowering plants found in Antarctica. As you can imagine, these fish have some interesting adaptations that allow them to live in such frigid waters. They can absorb water from a saturated atmosphere when covered by snow. Mystery Science offers an open-and-go elementary science unit suitable for 1st, 2nd, and 3rd grade covering Plant Adaptations: Activity Preparation –Thick waxy skin holds in water. arctic plant adaptations December 13, 2020 December 13, 2020 . What Are the Adaptations of Seaweed? The Antarctic Pearlwort has many adaptations that it needs to survive. As a result, we see almost a desert – landscape with rare patches of grass, mosses, and low-growing shrubs. Mosses in particular become more abundant, especially in wetter areas, and there are two higher plants (vascular plants) that can survive south of 60°S: Antarctic Hair Grass and Antarctic Pearlwort. They can be found on the South Orkney Islands, the South Shetland Islands, along the Antarctic Peninsula and sometimes even on the southernmost tip of Chile. Their optimum growth temperatures are below 10° C. Arctic plants tend to be small and grow low to the ground and can be coated with hair and wax to avoid wind chill. MATERIALS AND METHODS Xerophytes have adapted to be able to hold onto large amounts of water for a long period of time or limit water loss. This low species diversity may be due to the permanent low temperature even during summer time. They are Antarctic hair grass (Deschampsia antarctica) and Antarctic pearlwort (Colobanthus quitensis). Hair Grass lives between … These areas are called tundra. Antarctic hair grass Some adaptation of this plants are, it can tolerate temperature below zero degrees Celsius but it is barely functioning then. Abstract. The flora of Antarctica proper consists of 2 flowering plant species, about 100 species of mosses, and roughly 30 species of liverwort. Reading Time: < 1 minute < 1 minute By Staff Writer Last Updated Mar 25, 2020 9:38:03 AM ET. Antarctica Hair Grass (Deschampsia Antarctica) The Antarctica Hair Grass (Deschampsia Antarctica) is a flowering plant, one of only two types that exist in Antarctica. Only two native vascular plants, the Antarctic hair grass Deschampsia antarctica and a cushion-forming pearlwort, Colobanthus quitensis, survive south of 56°S. Adaptations The adaptations of an antarctic hair grass include; - Its leaf blades are folded when young, then developing into long stems - Adapted to survive extreme environments Human Impact The antarctic hair grass has not been massively affected by humans. Graciela Berríos, Gustavo Cabrera, Manuel Gidekel, Ana Gutiérrez-Moraga, Characterization of a novel antarctic plant growth-promoting bacterial strain and its interaction with antarctic hair grass (Deschampsia antarctica Desv), Polar Biology, 10.1007/s00300-012-1264-6, 36, 3, (349-362), (2012). Ecology, 84(6), 1415-1420. doi:10.1890/02-3154, 16. The first is the presence of an antifreeze glycoprotein in their blood and body fluids. In Antarctica, there are only 2 types of flowering plants: Antarctic pearlwort (Colobanthus quitensis) and Antarctic hair grass (Deschampsia antarctica). Antarctica - Antarctica - Plant life: The cold desert climate of Antarctica supports only an impoverished community of cold-tolerant land plants that are capable of surviving lengthy winter periods of total or near-total darkness during which photosynthesis cannot take place. Location: It is one of the only two higher plant species (of vascular and flowering plants) that can survive in Antarctica below 60˚S. Without these capabilities, the plants would die, as their arid environment does not provide enough water to sustain life. Poaceae (/ p oʊ ˈ eɪ s i aɪ /) or Gramineae is a large and nearly ubiquitous family of monocotyledonous flowering plants known as grasses.It includes the cereal grasses, bamboos and the grasses of natural grassland and species cultivated in lawns and pasture. AFGPs allow to avoid freezing by binding water molecules, thus preventing growth of ice crystals in the blood and … Hair grass and pearlwort grow in the South Orkney Islands, the South Shetland Islands and on the western side of the Antarctic Peninsula, according to the British Antarctic Survey (BAS).
