Phloem tissue consists of less specialised and nucleate parenchyma cells, sieve-tube cells, and companion cells (in addition albuminous cells, fibers and sclereids).

Phloem
In vascular plants, phloem is the tissue that carries organic nutrients, particularly sucrose. In trees, the phloem is part of the bark, hence the name, derived from the Greek word for "bark". See also xylem.

Phloem cells conduct food from leaves to rest of the plant. They are alive at maturity and tend to stain green (with the stain fast green). Phloem cells are usually located outside the xylem.

phloem -- Nutrient-conducting tissue of vascular plants.
phosphate -- an ion consisting of a phosphorus atom and four oxygen atoms. Among other things, it is used in the constuction of nucleic acids.

phloem
(floh-um) [Gk. phloos, bark]
The portion of the vascular system in plants consisting of living cells arranged into elongated tubes that transport sugar and other organic nutrients throughout the plant.

phloem: structures of vascular plants that transport sugars and other nutrients from the leaves to the other parts of the plant.
phosphate group: a group derived from a molecule of phosphoric acid that connects the DNA molecules to one another.

phloem rays The part of the vascular ray which is located in the secondary phloem.
phloem The food-conducting tissue of vascular plants, composed of sieve elements, various kinds of parenchyma cells, fibers, and sclereids.

phloem. The food-conducting tissue of a plant, made up of sieve tubes, companion cells, phloem parenchyma, and fibers.
phloem-feeding. An organism that withdraws nutrients from the food-conducting tissue of a plant's vascular system.

More on the phloem and food transport.
Cambium
During the growing season, mitosis in this band of meristematic tissue produces new phloem to the outside and new xylem to the inside.

Ramie is a bast fiber, and the part used is the bark (phloem) of the vegetative stalks. Unlike other bast crops, ramie requires chemical processing to de-gum the fiber.
