Though plants dont grow very high or very fast when the soil is limited in water and nutrients, some adaptations can help with this. Tundra Biome - National Geographic Society Tundra ecosystems are treeless regions found in the Arctic and on the tops of mountains, where the climate is cold and windy, and rainfall is scant. only a few plant species are able to adapt to its conditions. (The word tundra derives from the Finnish word tunturia, meaning barren or treeless hill.) Therefore tundra plants have evolved to get the most out of the short growing season. The plants living in the tundra are hardy plants. Cacti open their stomata at night to reduce water loss through transpiration. 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. This biome has a short growing season, followed by harsh conditions that the plants and animals in the region need special adaptations to survive. According to the National Geographic website, the summer growing season is only 50 to 60 days, although the sun shines day and night. They also shelter some of this same species.
