Question

Unique feature of plants growing in high mountains

Answer 1

The growth of vegetation depends on rainfall and temperature.
The vegetation on the lower slopes largely depends on which climate zone the mountain is in. The foothills may be covered in broadleaved forests. These change to needleleaf trees (coniferous trees) like spruce and pines at on the upper slopes (higher altitudes).
As you climb higher up a mountain it gets colder and the trees eventually thin out and disappear. When it gets too cold for trees to grow, it is called a timberline
