WebIn (right) typical monocots, the phloem cells and the larger xylem cells form a characteristic ring around the central pith. The cross section of a dicot root has an X-shaped structure at its center. The X is made up of many xylem cells. Phloem cells fill the space between the X. A ring of cells called the pericycle surrounds the xylem and phloem. WebPhloem is a complex tissue made up of various cell types; its bulk is made up of sieve tube elements which are the main conducting cells and companion cells Other cell types of phloem tissue also include parenchyma for storage and strengthening fibres Mature phloem tissue contains living cells, unlike xylem tissue Structure of phloem tissue.

WebCambium is a layer of unspecialised cells actively dividing for plant growth. In the stems of dicots, the vascular bundles are arranged in a ring-like structure around a cambium. Xylem is present in the cambium ring’s inner part, and phloem is present at the exterior. Sclerenchyma tissue comprises thin and narrow non-living cells (when mature). WebStructure Of The Phloem Tissue: This is a long tube that runs alongside the xylem tissue. They are made of long narrow tubes with perforated sieve plates along the thin length. The function of the phloem tissue is to transport food nutrients such as glucose and amino acids from the leaves and to all other cells of the plant, this is called translocation. flowers and chocolate delivery m\u0026sWebJose A.
