What groups of plants are found in the tundra. What is the remarkable structure of the leaves of the stems of the roots?

Tundra is a harsh northern area. About 400 species of plants grow here – these are undersized trees and shrubs, shrubs, mosses, lichens, sedges, a small amount of cereals. The growing season here is limited to only two months, and since most of the year the land is covered with ice, only vegetation with multiple small roots survives. Because of the frequent strong winds, most plants try to cuddle closer to the ground, very few are able to grow year-round, providing food for local animals.
