phlo·em

(flō′ĕm′)

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.

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.

The leaves of these cultivars showed high amounts of parenchyma and phloem, which are the main tissues in the diet of cattle because of their primary structure and thin cell walls; thus, the leaf anatomy can be a useful tool to assess the digestibility potential of a given forage (PACIULLO, 2002).

Mg is an essential element for the plant development, which is required in several metabolic processes and reactions, such as photophosphorylation, carbon dioxide fixation in photosynthesis, protein and chlorophyll synthesis, phloem loading, assimilate partitioning, reactive oxygen species formation and photo-oxidation in leaf tissues (CAKMAK; YAZICI, 2010).

Without xylem and phloem and with paper-thin leaves, mosses rely on direct contact with water to stay hydrated and nourished and to reproduce; male and female parts are separate, and the sperm -- not pollen -- needs water to swim to its target.

It also means that botany textbooks around the world will need to update their descriptions of how the two types of vascular tissues in plants -- xylem (better known as wood) that transports water and phloem that transports nutrients -- form, differentiate and grow.

In the four varieties, syncytia developed within the vascular tissues; specifically, they occupied part of the xylem and displaced the phloem to the periphery (Figures 2E, F); they produced reduction, rupture and fragmentation of those tissues.
