Is tundra biome is cold and almost treeless.?

Yes, the tundra biome is characterized by its cold climate and minimal tree growth. It features permafrost, a layer of permanently frozen ground, which limits root development and vegetation. The landscape is primarily dominated by mosses, lichens, low shrubs, and grasses, making it nearly treeless. The harsh conditions, including short growing seasons and strong winds, contribute to the unique ecology of the tundra.
