- How is the production of secondary meristems different in the shoot and the root?
- What are the tradeoffs (costs and benefits) to secondary growth?
- What is the function of a lenticel?
- Would roots in secondary growth need lenticels? Why or why not?
- What is the function of a xylem ray?
- How could you distinguish phloem fibers from other phloem cells? What cell type are phloem fibers?
- What type of questions could you answer with dendrochronology if you didn’t have a living reference specimen to connect the cores to the current date?
- Girdling is a process used to slowly kill a tree and/or to create a standing dead tree (a snag). Both the outer and inner bark of the tree is removed all the way around a section of the trunk. Often, this also removes or damages the vascular cambium.
- Explain why girdling would kill the tree.
