Question

Quizplus · Accepted Answer

Trees lose their leaves in the winter because both A and B are true. The shorter days mean the trees don't have enough light to drive photosynthesis, and when the ground freezes, they don't have enough water to support photosynthesis. Option C is incorrect because transpiration (the process by which water is taken up by roots and released through leaf pores during photosynthesis) can occur year-round as long as the temperature and humidity conditions are right.
