Critical Thinking Activities - Chapter 31

Question 1. Some evolutionary botanists propose that deciduous trees do not lose their leaves as a natural consequence of winter and water freezing, but in order for the tree to discard a season of fungus-infected leaves. Is this a reasonable hypothesis and what evidence might support it.

Answers are available to instructors in the Instructor's Manual.
