Pearson, as an active contributor to the biology learning community, is pleased to provide free access to the Classic edition of The Biology Place to all educators and their students.
The purpose of the activities is to help you review material you have already studied in class or have read in your text. Some of the material will extend your knowledge beyond your classwork or textbook reading. At the end of each activity, you can assess your progress through a Self-Quiz.

Concept 14: Lateral Meristems
In woody plants, secondary growth of stems and roots occurs through the activity of two lateral meristems: the vascular cambium and the cork cambium.
Use information in the graphic to answer the questions below it.
Secondary growth occurs in all gymnosperms and most angiosperms, including most dicots but few monocots.
1. From which cambium does the outer bark of a woody stem develop?
2. From which cambium does secondary xylem and secondary phloem develop?
3. Which cambium develops from parenchyma cells located between vascular bundles?
4. From which cells does fascicular cambium develop?
5. Which secondary meristem forms from the fascicular and interfascicular cambium?
