Critical Thinking

22. Applying Information When transplanting a plant, it is important to not remove any more soil than necessary from around the root system. From your knowledge of the function of roots and root hairs, why do you think this is so important?

23. Analyzing Data Suppose you examine a tree stump and notice that the annual rings are thinner and closer together 50 rings in from the edge. What would you conclude about the climate in the area 50 years ago?

24. Applying Information Why would an agricultural practice that eliminated transpirational water loss be disadvantageous for plants?

25. Evaluating Differences Would you expect water absorption in a plant to be greater in parts of roots that have undergone secondary growth or in parts that have not? Explain your reasoning.
