Detailed explanation-1: -Phloem (/ˈfloʊ. əm/, FLOH-əm) is the living tissue in vascular plants that transports the soluble organic compounds made during photosynthesis and known as photosynthates, in particular the sugar sucrose, to the rest of the plant. This transport process is called translocation.

Detailed explanation-2: -The phloem is the means by which the products of photosynthesis are transported to non-photosynthetic parts of the plant, such as the roots, and to developing leaves, nectaries, fruits and seeds (Baker and Milburn, 1989).

Detailed explanation-3: -The photosynthates from the source are usually translocated to the nearest sink through the phloem sieve tube elements. For example, the highest leaves will send sugars upward to the growing shoot tip, whereas lower leaves will direct sugars downward to the roots.

Detailed explanation-4: -Phloem transports products of photosynthesis from the leaves where they are synthesized to other parts.

Detailed explanation-5: -Xylem transports water and mineral salts from the roots up to other parts of the plant, while phloem transports sucrose(sugar) and amino acids between the leaves and other parts of the plants.
