| 31. | The end walls, unlike vessel members in xylem, do not have openings.
|
| 32. | Xylem sap consumption may be related to osmoregulation.
|
| 33. | The plant xylem sap may be able to detour around the cavitation through interconnections.
|
| 34. | Xylem tissues can be generated when the auxin concentration is equal to the cytokinins.
|
| 35. | Typically, cytokinins are transported in the xylem.
|
| 36. | The Winteraceae have no vessels in their xylem.
|
| 37. | The disease will spread into as well as between the cells of the xylem.
|
| 38. | This speculation arises due to the dilute and nutrient-poor character of xylem.
|
| 39. | Root pressure is caused by active distribution of mineral nutrient ions into the root xylem.
|
| 40. | The mycelium advances intracellularly through the xylem vessels and produce microconidia ( asexual spores ).
