The biodiversity in the tundra is very low relative to other biomes. In Arctic and alpine tundra ecosystems, the plant communities are influenced by soil drainage, snow cover and time of melt, and localized microclimates that differ from one another in temperature, wind, soil moisture, and nutrients. Plants of the same species often grow near each other in clusters in the tundra. Its leaves are oval-shaped and have a pointed tip, while its flowers are spiky with no pedals. The tundra only gets a small amount of precipitation each year, but plants in the tundra are specially adapted to only need a small amount of water to germinate and grow. One of the national flowers of both Austria and Switzerland, the snow gentian is a vascular, annual plant that thrives in the Arctic. This because the tundra soil is poor and has little nutrients. Charles Darwin posited that this process leads to the evolution of structural adaptations in a population that improve fitness and viability. Purple saxifrage grows low to the ground and traps in heat with its many hair covered leaves. Floating on Water. The top of the mixture of soil, gravel, and finer materials are frozen for the majority of the year since the temperatures don't increase high enough for it to thaw. Also, tundra plants face a huge challenge in terms of nutrients and grounding soil. Loss of water is a concern for plants in the desert; therefore many plants have adaptations in their leaves to avoid losing large quantities of water. Tundra has a very short summer.

Bearberry is an evergreen plant that belongs to the heather family. It also limits foliage damage from the impact of tiny particles of ice and snow that sweep through the tundra, driven by the harsh winds. Plants contain genetic material in the nucleus of their cells that is passed down through generations. Juniper are gymnosperms with sharp, pointed needles or waxy scales adapted for less water loss. ASU - Ask A Biologist, Web. But sedges did great in adapting to tundras harsh conditions. They start to sink because the hard ground they once rested on un-freezes and gets softer. Some plants are even red in color. Therefore tundra plants have evolved to get the most out of the short growing season. Yucca have a long tap root for accessing sources of water that competing species cannot reach. Tundras are cold, harsh environments with distinctive biodiversity adapted to these conditions. The following are the common characteristics which tundra plants developed to survive: Almost every plant in the tundra has a shallow root system.

Many trees in the rainforest have leaves, bark and flowers that are wax coated as an adaptation to handle excessive rainfall that can give rise to the growth of harmful bacteria and fungus. The plants have also developed the ability to carry out photosynthesis using sunshine to create energy in extremely cold temperatures and low light intensities. Examples of Arctic vegetation include willows, poppies and purple saxifrage. Because it grows near the ground, the tundra winds cant harm it. Willow clumps less than 60 cm (about 24 inches) tall are common in the krummholz (a transitional zone of scattered clusters of stunted trees) and beyond, where snowdrifts are extensive. The soil of the tundra is also nutrient poor, so it lacks nitrogen and phosphorus two important elements plants need to grow. Purple Mountain Saxifrage (Saxifraga oppositifolia).

Carbon is an element that makes up all living things, including plants. Algae and fungi are found along rocky cliffs, and rosette plants grow in rock cornices and shallow gravel beds. This special feature helps bearberry to retain moisture and survive the drought season. Habitats are classified into two domains: Terrestrial/ Land habitat and Aquatic/Water habitat. Tundra plants can grow and flower at lower temperatures than any other plants on earth. Diverse marine, aquatic and terrestrial plants evolved long before dinosaurs roamed the Earth. bladderwort plays an important role in the tundra ecosystem. Tropical rainforests receive 80 to 400 inches of rain a year, which can lead to bacteria and fungi growth, soil erosion, nutrient leaching and poor soil quality. Some plants grow with very little or no soil. It is also known for its intense blooms during the summer ( the growing season).

This surface supports a meagre but unique variety of . In Arctic and alpine tundras, the number of species of plants and animals is usually small when compared with other regions, yet the number of individuals per species is often high. Images via Wikimedia commons. The plant is perennial which means the pasque flower plant almost kills its upper part. Vegetation adaptation. From their humble beginnings as single-celled algae, plants have evolved clever adaptations to survive and reproduce even in the harshest environments. Many plants set few seeds and depend mostly upon runners or underground stems for increasing their numbers, such as a number of Arctic species in the heath family (Ericaceae). Today, flowering plants are ubiquitous around the world. The transition from mountain forest to the shrub- and herb-dominated alpine tundra at higher elevations is very similar to the transition from the coniferous forest belt to the Arctic tundra at higher latitudes. Animals living in the tundra regions have thick fur and extra layers of fat to keep them insulated. Yucca also have an adaptive reproductive process with the yucca moth that mutually benefits the life cycle of both species. Most tundra plants survive the harsh winter season by going dormant.
