Definitions and meanings of "Phloem"

What do we mean by phloem?

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. noun

In botany, the bast or liber portion of a vascular bundle, or the region of a vascular bundle or axis with secondary thickening which contains sieve-tubes. Compare xylem. noun

That portion of fibrovascular bundles which corresponds to the inner bark; the liber tissue; -- distinguished from xylem. noun

A vascular tissue in land plants primarily responsible for the distribution of sugars and nutrients manufactured in the shoot. noun

(botany) tissue that conducts synthesized food substances (e.g., from leaves) to parts where needed; consists primarily of sieve tubes noun

A vascular tissue in land plants primarily responsible for the distribution of sugars and nutrients manufactured in the shoot

Tissue found in vascular plants. Its main function is to transport sugars and other food materials such as amino acids (see protein) from the leaves, where they are produced, to all other parts of the plant. This could be from the leaves to the roots to provide the chemicals needed for growth. However, it could be from a leaf and up to a developing fruit that is rich in sugars. The sugars are made by photosynthesis, which occurs in green parts of plants, such as leaves (see leaf). The amino acids are made from sugars and minerals, such as nitrate absorbed from the soil. Phloem tissue is usually found close to the other transport tissue in plants, xylem, which transports water and minerals. In non-woody plants phloem and xylem are found in bundles, such as the veins of a leaf. Phloem is composed of sieve elements and their associated companion cells, together with some sclerenchyma and parenchyma cell types. Sieve elements are long, thin-walled cells joined end to end, forming sieve tubes; large pores in the end walls allow the continuous passage of nutrients. Phloem is usually found in association with xylem, the water-conducting tissue, but unlike the latter it is a living tissue. Urban Dictionary
