When will a plant use symplastic path or apoplastic path for conducting water?

Solutes move between cells either through the extracellular spaces (the apoplast) or from cytoplasm to cytoplasm (via the symplast).Cytoplasms of neighboring cells are connected by plasmodesmata, which facilitate symplastic transport.When an ion enters the root, it may be taken up into the cytoplasm of an epidermal cell, or it may diffuse through the apoplast into the root cortex and enter the symplast through a cortical cell.From the symplast, the ion is loaded into the xylem and transported to the shoot.
