The type of vegetation most commonly found in a tundra biome includes mosses, lichens, low shrubs, and sedges. This biome is characterized by harsh climates, with extreme cold and limited precipitation. The vegetation is adapted to short growing seasons and low temperatures, growing close to the ground to escape harsh winds. The presence of permafrost influences root growth, leading to the dominance of these low-lying forms of vegetation which are crucial for soil stability and providing habitat for various species.
