| 1. | Before the cortex is destroyed, a cork cambium develops there.

| 2. | The vascular cambium produces new layers of secondary xylem annually.
|
| 3. | The parent cells of the vascular cambium produce both xylem and phloem.
|
| 4. | Between the xylem and phloem is a meristem called the vascular cambium.
|
| 5. | The unifacial cambium allowed plants to grow as tall as 50 metres.
|
| 6. | Xylem tissue in unifacial cambium plants was particularly structurally efficient.
|
| 7. | Pocket gophers often feed on the cambium of young canyon live oaks.
|
| 8. | These xylem strands have a cambium, and a secondary phloem forms.
|
| 9. | Young larvae begin feeding and mine downward in the cambium.
|
| 10. | So far, though, Cambium still is shopping for an American distributor.
