Unformatted text preview: conductive pathways-- apoplast or symplast. With the apoplast, water travels along cell walls and through intercellular spaces from the root surface to the core. The symplast route, on the other hand, moves fluids through the cells, via channels that connect their contents. Stem and Trunk Plant stems function in various capacities, primarily in nutrient transport and physical support. The vascular system of plants, complete with xylem and phloem, fills both purposes. Stems, along with roots, also store food for the plant. Pith, a tissue that lies in the center of the stem (or, as it is called in trees, the trunk), is responsible for some nutrient storage as well....
