Coordinated analyses of Antarctic sediments as Mars analog materials using reflectance spectroscopy and current flight-like instruments for CheMin. Through this process, plants capture the suns energy and use it to fuel chemical reactions that convert carbon dioxide and water into oxygen and energy-containing carbohydrates (sucrose, glucose, or starch). These succulent leaves are packed with moisture to help them endure dry desert terrain. Familiar desert plants include cacti, euphorbias and succulents, which all store water and use it sparingly.

There are five major types of biomes: aquatic, grassland, forest, desert, and tundra, though some of these biomes can be further divided into more specific categories, such as freshwater, marine, savanna, tropical rain forest, temperate rain forest, and taiga. With such little precipitation, its not easy for anything to live in a polar desert but there is life! The plant has a thick trunk with branches that grow at the top. Plants also grow close to the ground and to each other, a strategy that helps to resist the effects of cold weather and reduce damage caused by wind-blown snow and ice particles. The globular, low-growing plant may eventually reach 3 ft. (1 m) in height. Fungi do not produce energy through photosynthesis but instead obtain food by breaking down and absorbing surrounding materials.

In the past these lichens have been used for food by starving explorers. Malaska et al. As a result desert animals and plants cannot rely on the presence of moisture for their growing or reproductive seasons they must first wait for rain to arrive before completing their life cycles. Characteristics of polar environmentsthe climate, substrates, elevation above sea level, slope, exposure, and proximity to other landmassesdetermine the complex of plant and animal life present in the polar regions. More than half of desert animal species spend the majority of their time underground, either sleeping or hibernating. Its not just cacti and succulents that can survive hot desert weather.
