WebbOsmotic adjustment participates in plant stress tolerance and development mechanism; e.g., Ca 2+ translocation in and out from the vacuole, cell wall, and intercellular compartments regulate the development of phloem ganglion in P. edulis during the active early growth phase. WebbThe xylem transports water taken up from the soil by the roots, to the rest of the plant. Phloem transports assimilates (substances made by the plant) from the source (i.e. areas where they are produced, like leaves) to a sink (areas where they are used or stored, like the root or the flower).
