which of the following describes the role of phloem in a vascular plant?

phloem: a vascular tissue in land plants primarily responsible for the distribution of sugars and nutrients manufactured in the shoot . 

Phloem is responsible for transporting sugars, proteins, and other organic molecules in plants. Phloem tissue is responsible for translocation, which is the transport of soluble organic substances, for example, sugar. The substances travel along sieve elements, but other types of cells are also present: the companion cells, parenchyma cells, and fibers. The end walls, unlike vessel members in xylem, do not have large openings. The end walls, however, are full of small pores where cytoplasm extends from cell to cell. These porous connections are called sieve plates. Despite the fact that their cytoplasm is actively involved in the conduction of food materials, sieve-tube members do not have nuclei at maturity. The activity of the sieve tubes is controlled by companion cells through plasmadesmata.
