Why are most plants that grow in the tundra small with thin, wax-covered leaves?
1 answer
Plants that grow in the tundra have to adapt to the harsh climate conditions of the region. The short growing season, low temperatures, and constant exposure to harsh winds make it difficult for plants to survive. Therefore, most plants that grow in the tundra are small with thin, wax-covered leaves as these adaptations help them to conserve energy and withstand the harsh environment. The small size and low profile of these plants reduce their exposure to the wind and minimize water loss due to transpiration. The wax-covered leaves help to prevent moisture loss due to evaporation, which is critical given the limited amounts of moisture available in the tundra. By adapting to these harsh conditions, the plants that grow in the tundra are able to thrive in what is otherwise a very challenging environment for life.
