Detailed explanation-1: -Plants which grow in the tundra include grasses, shrubs, herbs, and lichens. These grow in groups and stay low to the ground for protection from the icy winds. Also, these tend to have shallow roots and flower quickly during the short summer months.

Detailed explanation-2: -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-3: -Tundra vegetation is composed of dwarf shrubs, sedges, grasses, mosses, and lichens. Scattered trees grow in some tundra regions.

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.

Detailed explanation-5: -The tundra does not have much biodiversity and vegetation is simple, including shrubs, grasses, mosses, and lichens. This is partly due to a frozen layer under the soil surface, called permafrost.
