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 ).
