Permafrost is in the Arctic and subarctic. There is a Permafrost Scientific Research Station located at Skovorodino in Eastern Siberia on the Trans-Siberian Train line.
Hey man, I'm not doing your homework for you. Do it yourself!
It comes and goes every 2 years.
I think that the Yakutsk region is the coldest region, even colder than Siberia.
The tundra biome is known for having permafrost, which is a layer of frozen soil that remains frozen year-round. This layer of permafrost poses challenges for plant roots and contributes to the unique landscape of the tundra.
It is not so much that permafrost is good, as losing permafrost is bad. Permafrost keeps gases like carbon dioxide trapped within its frozen depths; when permafrost thaws, that gas is released, exacerbating global warming. Further, permafrost develops its own ecosystem which is destroyed when the permafrost is destroyed through thawing. The loss of all permafrost would mean the extinction of a lot of species.
Tundra exists where the subsoil is permafrost (permanently frozen) and/or where tree growth is hindered by low temperatures and short growing seasons. It exists in three locations: Arctic (mainly northern Canada and Russia), Alpine (on mountains worldwide), and Antarctic (Antarctica and islands near the continent).

The key environmental limitation in Russia's Siberian region is permafrost. Permafrost makes it difficult to conduct human activity such as construction or agriculture. Another key difficulty is that in some northern latitudes water must be heated to remain usable to humans and animals.
Siberia encompasses more than half the territory, but is home to less than 20 percent of the population.
Taiga is a cold place but it does not have permafrost. So the grass and trees can grow there. In the northern part of Russia there are thick forests and they are called Taiga. In Tundra, there is permafrost and the possibility of growing any plantation is zero. The Tundra is located near to the northern pole.
No, nothing grows in permafrost because during permafrost, the ground is permanently frozen
