Arctic Plants There are around 1,700 species of plants living in the Arctic tundra and Arctic desert. This includes a range of flowering plants, dwarf shrubs, herbs, grasses, mosses, and lichens.
Tundra is found at high latitudes and at high altitudes, where the permafrost has a very thin active layer. The active layer of tundra is too thin for trees to grow, because it cannot support a tree’s roots.

Animals living in the Arctic tundra have developed adaptations including heavy winter coats, camouflage that changes color with the seasons, efficient body shape to prevent heat loss and the ability to build insulated tunnels underground.
Why can’t trees grow in the Arctic?
Under a thin soil layer exists permanently frozen ground, or permafrost. The existence of contiguous permafrost is thought to be one of the main reasons why there are no trees in the tundra, because, being permenantly frozen, permafrost has a tendency to hamper root development.
How do plants survive in the desert?
The leaves and stems of many desert plants have a thick, waxy covering. This waxy substance does not cover the stomata, but it covers most of the leaves, keeping the plants cooler and reducing evaporative loss. Small leaves on desert plants also help reduce moisture loss during transpiration.

How do plants survive in the rainforest?
They have adapted to life in the rainforest by having their roots in the ground and climbing high into the tree canopy to reach available sunlight. Many lianas start life in the rainforest canopy and send roots down to the ground. The leaves of forest trees have adapted to cope with exceptionally high rainfall.
