WebbFood is synthesized in the green parts of a plant. The non-green parts are depended on the photosynthetic cells for nourishment. The food in the form of sucrose is transported by the vascular tissue phloem. Let us learn a bit more about phloem transport. WebbWhere does the phloem get food that it carries to the stem and roots? The vascular system is comprised of two main types of tissue: the xylem and the phloem. The xylem distributes water and dissolved minerals upward through the plant, ... The cells that do this work are called the xylem cells.
