Antarctica is too cold and dry for agriculture or for growing anything. Within a few hours, the cactus would freeze.
Cacti are natives of the Americas only and would not be found in the Gobi Desert of Asia unless man planted then there.
It would probably suffer from root rot and die. The cacti are not water plants.
Cacti would have to be planted in pots and moved indoors during cold, wet weather or planted in a heated greenhouse.
It would grow.
