Why do some plants in the tundra retain their dead leaves instead of shedding them?

• A. To increase the rate of photosynthesis during winter
• B. To attract pollinators during the short growing season
• C. To provide insulation and protect living tissues from cold temperatures
• D. To store excess water for use during dry periods

Answer: (C)

Verified step by step guidance

1. Understand the environmental conditions of the tundra biome: The tundra is characterized by extremely cold temperatures, strong winds, and a short growing season. These conditions make survival challenging for plants.
2. Recognize the role of adaptations in plants: Plants in the tundra have evolved specific adaptations to survive harsh conditions, such as retaining dead leaves to serve a functional purpose.
3. Analyze the function of dead leaves: Dead leaves can act as insulation, reducing heat loss and protecting living tissues from freezing temperatures during the winter months.
4. Eliminate incorrect options: Retaining dead leaves does not increase photosynthesis during winter, as photosynthesis is limited due to low light availability. Similarly, dead leaves do not attract pollinators or store excess water, as these functions are not relevant to tundra survival.
5. Conclude the correct answer: Retaining dead leaves provides insulation and protects living tissues from cold temperatures, which is a critical survival strategy for plants in the tundra.
