Phloem, and xylem, tissue is arranged so that cells join end to end to form long tubes throughout the plant.

Unlike xylem (which is composed primarily of dead cells), the phloem is composed of still-living cells that transport sap. The sap is a water-based solution, but rich in sugars made by photosynthesis. These sugars are transported to non-photosynthetic parts of the plant, such as the roots, or into storage structures, such as tubers or bulbs. WebbThe phloem is the vascular tissue that carries out the function of translocation (i.e the process of transporting photosynthate materials from the photosynthetic plant organs to various parts of the plant.
