Study Questions (from Lab Manual)

1. What are the types of meristems based on position? Give examples of each.

2. What is the tunica-corpus theory? Who was its proponent

3. How can you recognize the three corpus zones in the shoot apical meristem? What causes the differences in the staining properties of the three zones?

4. What are the differences between the vascular cambium and the cork cambium?

5. Differentiate and describe the vascular cambium and cork cambium.
