Detailed explanation-1: -Plants like lichens and moss can survive on bare rock with a bit of moisture. Most of the plants in the Tundra Biome are peren-nials and don’t die off in the winter, they have long life cycles to help with the short growing season.

Detailed explanation-2: -Instead, the tundra has patchy, low-to-ground vegetation consisting of small shrubs, grasses, mosses, sedges, and lichens, all of which are better adapted to withstand tundra conditions.

Detailed explanation-3: -Definition: A type of ecosystem dominated by lichens, mosses, grasses, and woody plants. Tundra is found at high latitudes (arctic tundra) and high altitudes (alpine tundra).

Detailed explanation-4: -Tundra winters are long, dark, and cold, with mean temperatures below 0°C for six to 10 months of the year. The temperatures are so cold that there is a layer of permanently frozen ground below the surface, called permafrost. This permafrost is a defining characteristic of the tundra biome.
