Detailed explanation-1: -One of the biggest characteristics of the tundra is its lack of trees. It is known for not having any trees due to its very nutrient-poor soil, little precipitation, and being covered by frost and snow. Most of the year the tundra is frozen, but there is a short growing season.

Detailed explanation-2: -As there is little soil, only some small plants can grow. The underground soil being hard does not allow trees to grow. The land cannot grow trees.

Detailed explanation-3: -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-4: -A. TUNDRA: treeless low (less than 1 m) vegetation with short perennials, water frozen. Typical plants include sedges, lichens, mosses, grasses, and dwarf woody plants.

Detailed explanation-5: -Some plants that grow in the tundra include short shrubs, sedges, grasses, flowers, birch trees and willow trees.
