Answer:Adaptations in Plants That Grow in Snowy Regions
1) Most of these plants are present with specialised adaptations that help them to survive in harsh climatic conditions. Those adaptations are - Their needles are long and thin. This means that they have a small surface area. Less surface area means that they have fewer stomata from which to lose water. Narrow leaves also help keep snow from building up and breaking branches.
2)Their stomata are not on the surface of the needle, but rather are deep within the needle. This creates a pocket of still air just inside the needle. Still air results in less transpiration than moving air.
3) Their needles have thick, waxy cuticles. The cuticle is the outermost part of a leaf. The wax helps to prevent water loss. Think of how wax paper wrapped around food keeps it from drying out.
4) Trees also produce antifreeze proteins. These proteins help prevent ice crystals from forming in cold temperatures.
