GENERAL KNOWLEDGE

Detailed explanation-1: -The tundra biome is a region in the Northern hemisphere where the trees do not grow due to the presence of lower temperature and permafrost soil. It also hinders the growth of plants due to their shorter growing seasons. It only consisted of short grasses, sedges, lichens, mosses, or small shrubs.

Detailed explanation-2: -Tundra is found in the regions just below the ice caps of the Arctic, extending across North America, to Europe, and Siberia in Asia. Much of Alaska and about half of Canada are in the tundra biome.

Detailed explanation-3: -Typically, only patches of moss, lichen, Arctic poppy (Papaver radicatum) and cold-hardy vascular plants such as sedge and cotton grass are found. Recent records have identified around 400 species of vascular plants in the region, represented in 42 families and 141 genera of plants.

Detailed explanation-4: -Tundra soil is also scarce in many of the nutrients that plants need to grow. These conditions lead to one of the tundra biome’s most distinct features: They are largely treeless. (The word “tundra” derives from the Finnish word tunturia, meaning barren or treeless hill.)
