Permafrost is the frozen liquid or gases on Mars, that never melt. While Mars' polar ice caps do shrink and grow, there are portions of it that never melt. This is the permafrost.
It is frost that never melts (ie permanent frost).
It is known as the permafrost.
Below permafrost is below freezing temperature (0c)
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.
Approximately 50% of Canada's land area is covered by permafrost.
"The permafrost makes maintaining the Alcan Highway difficult."
We don't know if there was life on Mars, but we have found evidence of water in a permafrost layer and at the poles, plus other indicators. There is the possibility that there was once life on Mars, but right now that's all it is, a possibility.
No, nothing grows in permafrost because during permafrost, the ground is permanently frozen

Only Antarctica or the tundra would have permafrost.

• as permanent frost (called permafrost) Water exists in ice form as permanent frost in the North and South Poles of Mars. The big slabs of ice are called polar icecaps. • as liquid So far, no liquid water has been found anywhere on Mars.
