There are two types of tundra-arctic tundra and alpine tundra. The arctic tundra is located within the Arctic Circle while the alpine tundra is the area high in the mountains above trees. The plants that grow in the tundra biome often grow in clusters to help protect themselves from the severe winter winds.here are very few trees that grow in the tundra biome. Under the snow and ice, there is a thick layer of soil that remains frozen which does not allow deep rooted plants such as trees to grow. The tundra biome has about 400 varieties of flowers but only 48 different animals.
