Question: what is the effect of elevation on the quality of plants?
for example why is green tea grown in high altitude?

Different altitudes have different characteristics which form different
ecological zones
And each ecological zone will have its own physical characteristics.

For instance, the high alpine eco-zone has colder temperatures, and more
precipitation in the form of snow favoring tall trees, or maybe excluding
tall trees and favoring the development of moss and lichens.
Lower eco-zones would have higher temperatures, and possibly lower
precipitation levels.
So you take these factors and mix them up, lo-altitude, hi precipitation;
hi-altitude, low precipitation and on and on.

Also, the higher the altitude, the lower the air pressure.

Plants develop in eco-zones and develop the special characteristics that
allow it to thrive in that eco-zone.  Take a plant out of the high mountains
and plant it in the desert, and it might not survive.

For instance cactus has waxy surfaces and thrive in hot, low precipitation
Whereas redwood trees thrive in areas of high precipitation in the form of
coastal fog.

So plants will thrive best in their native eco-zone.  So, now you can make
an educated guess as to why green tea is grown at high altitudes. A:
because that is where the temperature, rainfall and soil mineral and texture
suit the green tea plant.  :)

Sincere regards,

The following may be helpful: "Many high-quality tea plants are cultivated at elevations of up to 1500 meters (5,000 ft): at these heights, the plants grow more slowly and acquire a better flavour." Sincerely,
