Microsoft Rewards Bing Homepage Quiz Question: What’s unusual about the bark of a quaking aspen?
The given options are:
- It ‘trembles’ just like the leaves
- It photosynthesizes year-round
- It changes color in winter
Correct Answer: It photosynthesizes year-round
Info: While some other tree species can photosynthesize through a green chlorophyll layer in their bark, aspen bark has much more chlorophyll than any other species. This allows aspens to synthesize sugars and keep growing even in winter, when other deciduous tree species go dormant.
