phlo·em

 (flō′ĕm′)
n.
The tissue of vascular plants that conducts food produced by photosynthesis to all parts of the plant and consists of sieve elements, fibers, and parenchyma.

[German, from Greek phloios, bark; see bhleu- in Indo-European roots.]

phloem

(ˈfləʊɛm)
n
(Botany) tissue in higher plants that conducts synthesized food substances to all parts of the plant
[C19: via German from Greek phloos bark]

phlo•em

(ˈfloʊ ɛm)

n.
the part of a vascular bundle consisting of sieve tubes, companion cells, parenchyma, and fibers and forming the food-conducting tissue of a plant.
[< German (1858), irreg. < Greek phló(os) bark (variant of phloiós) + -ēma deverbal n. ending]

phlo·em

(flō′ĕm′)
A tissue in vascular plants that conducts food from the leaves to the other plant parts. Phloem consists primarily of tube-like cells that have porous openings. In mature woody plants it forms a sheath-like layer of tissue in the stem, just inside the bark. See more at cambium, photosynthesis. Compare xylem.

phloem

Tissue that carries food in plants.

Whereas thin-walled phloem cells are usually destroyed by charring to leave a mass of solid carbon, or sometimes a cavity (Hather 1991), xylem elements are commonly preserved at least partially intact, so that their features and arrangement within parenchymous tissues are useful for making broad characterisations regarding the composition of a charred macrobotanical assemblage.
