The tundra only gets a small amount of precipitation each year, but plants in the tundra are specially adapted to only need a small amount of water to germinate and grow. 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. . The pretty Yellow Marsh Saxifrage is often found in Arctic bogs. This is a perennial plant that adapts to the tundra hard conditions through going dormant in the winter season. Since mosses do not have roots and stems. But there are still plants out there. The topsoil remains frozen most of the year, and the permafrost can be hundreds of feet thick.

The foggy tundras found along coastal areas produce matted and grassy landscapes. The tundra is a treeless biome in which low temperatures and short growing seasons limit plant growth above a certain height. Plants like little shrubs, different types of mosses, lichens, sedges, and about four hundred flowering plants that vary in colors. Most show a small leaf structure as well. Atop the food chain are tundra carnivores, such as arctic foxes (Vulpes lagopus), arctic wolves (Canis lupus), snowy owls (Bubo scandiaca), and polar bears (Ursus maritimus), which move into the tundra during the summer when prey is plentiful and their usual hunting grounds on sea ice diminish. . While plants do not remain in flower for more than a few days or weeks in these environments, the blossoms are generally large in relation to the size of the plant and are rather colourful, especially in alpine habitats. The tundra biome is a cold and treeless plain where harsh conditions make it hard for plants and animals alike to survive. Lichens, which are made up to fungi and algae, grow on rocks.
