A slow growth rate expends less energy and helps preserve water. The flower turned out to be Yellow Marsh Saxifrage (Saxifraga hirculus), a perennial herb with yellow flowers and red stem (reaching anywhere from 5 to 30 centimetres high) and commonly found in bogs. Such specific adaptive strategies have evolved to help desert plants cope with conditions inhospitable to most living organisms. In southern latitudes, the plant grows up to 5 feet tall. Related to the rhododendron, Labrador tea is common in wet bogs and lower-latitude forested areas of the tundra biome. The tundra is characterised by a total lack of trees and has, instead, stubby vegetation that grows very slowly. TUNDRA ADAPTATIONS Size and Shape snow and avoid the most severe conditions of winter. Floating on Water. Larch forests survive in places too cold and barren for conifers. They insulate the permafrost from heat and help in keeping it frozen all year round. Nature Climate Change, vol. Some of those leaf adaptations are: (1) hairy or fuzzy leaves, (2) small leaves, (3) curled-up leaves, (4) waxcoated leaves, and (5) green stems but no leaves. Though still vibrant, these flowers have a lighter color than other poppy species, which helps them camouflage with their arctic environment. The taiga, also called the boreal forest, is a once glaciated area within Eurasia and North America that has retained patches of permafrost. The soil in the Arctic is largely permafrost or soil that remains frozen year-round, leaving only a thin surface layer of thawed soil in summer for plant roots to grow in. There are two soil layers in the tundra one that beneath the surface soil which called permafrost. Plants grow very fast in the growing season starting from blooming to setting their seeds.
