Constituents of Phloem

What are the Constituents of Phloem ?

Phloem is a complex plant tissue responsible for the transportation of nutrients, sugars and other essential substances throughout the plant. Phloem constituents include sieve tubes, companion cells, phloem fibers and phloem parenchyma cells. Sieve tubes are long, thin cells that form a continuous pipeline for the transport of sap. Companion cells provide support and metabolic assistance. Phloem fibers and phloem parenchyma cells provide structural support and storage capabilities.
