Plants that reproduce sexually in extremely cold environments may utilize seed dormancy to ensure survival. Once seed dormancy is broken, some seeds can rapidly germinate. Unlike animals, plants cannot escape the harsh winter climates. Plants in extreme heat can take advantage of the cold nights in their use of the CAM photosynthesis pathway. Although this season may be referred to as “summer,” the temperatures are still relatively low. To break dormancy, seeds may need to endure scarification, a “chilling period” or experience warmer temperatures. Plants respond to seasonal changes with behaviors such as dormancy, losing leaves, and storing food. In addition to their leaves, plants in hot and dry climates often have shallow root systems that take up nutrients in the top layer of soil while also taking advantage of little rainfall. (2002). In these areas, xerophytes thrive. Quiz & Worksheet Goals. A 60 second guide to plant adaptations (extreme cold).

Due to the heat from the sun, high rate of evaporation, and low rainfall, the air and soil in these regions are very dry. planet’s habitats and makes it possible to truly appreciate just how extreme the contrasts are between the environments the planet’s animals call home. Plant Adaptations. Plants go through dormancy during the winter months because there is a lack of sunlight, which they use for photosynthesis. For certain species, this could be temperature. They also found that CO2 concentrations are actually elevated under the snow because the gasses get trapped. Extremely cold environments are typically characterized by temperatures ranging between -50° C and -20°C. For example, in the Blepharis species, the seed can germinate just one hour after being exposed to water. In areas where rainfall is sporadic and unpredictable, an important adaptation is phenotypic plasticity of germination. For plants in cold environments, a majority of photosynthesis occurs during the summer months, when snow melts and the leaves are exposed to direct sun rays. Within the mesophyll cells of the leaves, the chloroplasts have increased cell surface areas due to irregular invaginations and pockets. The special characteristics that enable plants and animals to be successful in a particular environment are called adaptations. A number of factors can contribute to the readiness of a seed to germinate. Read About Adaptations DEFINITIONS OF PLANT & ANIMAL ADAPTATIONS An adaptation is a characteristic of a living thing that helps it survive in its environment. Another way that plants structurally gain protection is by growing in clustered groups or in a dense, mat like morphology16.

Desert areas are located in lower altitudes and on valley floors. Gielwanowska (2005) also investigated photosynthesis adaptations in this plant and found structural changes within their cells. Under the canopy of the tree, the soil contains hydrophobic organic acids. Secondary metabolites not only deter herbivores but may help plants deal with oxidative stress as a result of drought and high levels of irradiance from the sun13. Sexual reproduction promotes genetic diversity and may be beneficial to plants in extreme environments as natural selection can then favor the traits that increase fitness. Rinnan, R., Steinke, M., Mcgenity, T., & Loreto, F. (2014). In their study, they found that the snow often acts as an insulator, in which temperatures in the subnivean environment are warmer than those above the snow. For example, some seeds need to be exposed to extreme fluctuations in temperature between night and day in order for the seed coat to split. Other small, herbaceous plants with shallow roots cannot grow under the canopy of the tree because of this modification, and therefore the tree does not need to compete for water, a scarce resource14.

Retrieved December 14, 2016, from http://www.arkive.org/antarctic-hair-grass/deschampsia-antarctica/, 4. Roots and some parts of stems and leaves in these plants may be submerged in water or buried m mud but some foliage, branches and flowering shoots spring well above the surface of water or they may spread over the land (Fig. Adaptations of Hydrophytes: Morphological adaptations of hydrophytes, Anatomical adaptations of hydrophytes, Physiological adaptations of hydrophytes In some plants, day length influences when the plant flowers; when the day length is longer, and the seedling germinates with rainfall, there is a shorter time between germination and flowering. Tundra – Ecology. American Journal of Botany, 87(5), 700. doi:10.2307/2656856. Once re-exposed to water, the roots can regrow9. These plants will flower a certain amount of time after germination, regardless of the day length9. They are able to absorb water quickly for storage when rainfall occurs7.
