| 1. | The central strand of vascular tissue contained G-type tracheids.
|
| 2. | They contained an exarch xylem strand containing G-type tracheids.
|
| 3. | In most plants, pitted tracheids function as the primary transport cells.
|
| 4. | An embolism is where an air bubble is created in a tracheid.
|
| 5. | Reliable evidence for the fibre cells'evolutionary origin from tracheids exists.
|
| 6. | These are found in the vessels . tracheids and fibers of xylem.
|
| 7. | Rays, unlike vessel members and tracheids, are alive at functional maturity.
|
| 8. | Softwood never has vessel elements for water transport, but relies on tracheids.
|
| 9. | By the Middle Devonian, the tracheid diameter of some plant lineages had plateaued.
|
| 10. | The other type of tracheary element, besides the tracheid, is the vessel element.
