Why are most plants that grow in the tundra small with thin, wax-covered leaves?(1 point)
Most plants that grow in the tundra are small with thin, wax-covered leaves because they need to adapt to the harsh conditions of the tundra, where the growing season is short and the temperatures are low. As a result, they have developed a number of adaptations that allow them to survive, such as growing close to the ground to avoid wind and extreme temperature fluctuations, having small leaves to reduce water loss due to the cold, and having a thick layer of wax on their leaves to protect them from the wind and cold. Additionally, since the tundra is a fragile ecosystem, plants have adapted so they can survive in the nutrient-poor soil that is available there.

which answer is correct?
I apologize for my incorrect responses. The correct response is: Most plants that grow in the tundra are small with thin, wax-covered leaves because they need to adapt to the harsh conditions of the tundra, where the growing season is short, the temperatures are low, and the soil is nutrient-poor. Additionally, plants in the tundra need to protect themselves from the wind, which can be strong and frequent.
Most plants that grow in the tundra are small with thin, wax-covered leaves because they have adapted to survive in the harsh conditions of this environment. The tundra is characterized by low temperatures, strong winds, and a short growing season. These factors limit the availability of resources for plants, such as water and nutrients.
The small size of tundra plants helps to minimize the surface area exposed to the cold temperatures and winds, which helps to conserve water and reduce the risk of damage from freezing. Additionally, their small size allows them to grow close to the ground, where they can benefit from the insulation provided by snow cover.
The thin, wax-covered leaves of tundra plants serve several purposes. Firstly, the waxy layer, called cuticle, helps to reduce water loss through evaporation, as it acts as a barrier and prevents excessive transpiration. This is important since water availability is limited in the tundra. The cuticle also provides some protection against wind and cold temperatures.
Furthermore, the thin leaves allow for efficient gas exchange between the plant and the environment. In the tundra, the growing season is short, so plants need to perform photosynthesis quickly and efficiently in order to produce energy. The thin leaves maximize the exposure of chloroplasts to sunlight and allow for the rapid exchange of gases like carbon dioxide and oxygen.
Overall, the small size and thin, wax-covered leaves of tundra plants are adaptations that help them to survive and thrive in the challenging conditions of the tundra environment.
