A。解析:分生组织(Meristematic tissue)具有分化能力,可以分化成木质部(xylem)和韧皮部(phloem)等组织。表皮组织(Epidermal tissue)主要起保护作用,不能分化成木质部和韧皮部,B选项错误。基本组织(Ground tissue)主要执行储存、支持等功能,C选项不符合。永久组织(Permanent tissue)已经分化成熟,不具备再分化成木质部和韧...
Xylem and phloem are two distinct vascular tissues found in plants. Xylem primarily transports water and minerals from the roots to the rest of the plant, while phloem primarily carries sugars and other organic compounds produced through photosynthesis. Xylem consists of dead cells and operates throug...

What is the main function of xylem and phloem? The main function of xylem and phloem is transportation of substances throughout plants. Phloem carries sugar and nutrient sap and xylem carries water and minerals up from roots. Xylem also provides support to plants and is the primary material in...
The xylem and phloem tissues of plants represent substantial nutrient resources for biophages. The vascular plants, which parasitize xylem are in many respects nutritionally similar to the shoot of the host. Acquisition of xylem sap, containing the water needed for transpiration and growth and the ...
