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: -Sparse vegetation of lichens, herbs, and dwarf shrubs (especially Arctic willow, mountain avens, and plants in the heath family) is characteristic of this ecoregion. Low, wet areas, such as along streams and in deltas, often have a dense growth of sedges (e.g., cottongrass) and grasses.
