Scientific definitions for phloem
[ flō′ĕm′ ]
A tissue in vascular plants that conducts food from the leaves and other photosynthetic tissues to other plant parts. Phloem consists of several different kinds of cells: sieve elements, parenchyma cells, sclereids, and fibers. In mature woody plants it forms a sheathlike layer of tissue in the stem, just inside the bark. See more at cambium photosynthesis. Compare xylem.
