Few plants (and animals) survive in the Atacama Desert, including the mountains.
There is no significant farming in the Atacama. In a few areas near the rare aquifers there are some small operations that grow some tomatoes and cucumbers for the local markets.
Because of the lack of precipitation the variety of plant life in the Atacama is low. Plants are able to grown only in limited areas.

Cacti can not grow in most areas of the desert. However, there are a few areas that receive dense fog off of the Pacific Ocean and the condensation from this fog allows cacti to grow in these areas.
You might mean a desert.
Mountains, even when surrounded by desert, usually receive more rainfall than the surrounding desert and are able to support more plant life.
Generally, the mountains receive more precipitation than does a desert so more plants are able to grow there.
BECOUSE CACTI CAN NOT GROW IN COLD and high places
There is virtually no water in the Atacama so food cannot be grown there. Drinking water must be piped in from elsewhere and food trucked in from other areas. There is very little employment available except for some mining operations. Building materials for homes must be brought in from the outside. The weather is actually quite pleasant but living conditions are very difficult because of the location.
Mountains in Big Bend country were formed by the collision of tectonic plates millions of years ago, resulting in the uplift of the land. Over time, erosion and weathering shaped these mountains into the rugged landscape we see today.
There are areas that receive little rain but dense fog moves in from the Pacific Ocean and provides enough moisture for lichens and a few cacti to survive. There are rare oasis were a few more plants can survive but these are quite uncommon. Most of the desert is devoid of plant life, however.
If there is moisture available algae can grow in the desert.
