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?
