And only keep its roots alive under the ground to survive the winter. Biomass: living matter. Tundra form in two distinct cold and dry regions. Cushion plants resemble clumps of moss clinging to the ground. However, these forms of vegetation have special adaptations that enable them survive in the tundra. The ground is called permafrost if it has been frozen for longer than two years. Charles Darwins theory of evolution helps explain how plant adaptions occur as the result of inherited physical and behavioral characteristics passed down from parent to offspring. For most of the year, the tundra biome is a cold, frozen landscape. This is why plants as well animals in the Arctic tundra biome endure its testing conditions. Many tundra species cannot be found elsewhere, and thus the biome is an important contributor to global biodiversity despite its low species number. Also, tundra plants face a huge challenge in terms of nutrients and grounding soil. To say these plants must be frost hardy is obvious; they also face extreme cold, a short growing season, drought, frost heaving, strong wind, and infertile soil.
