A vascular bundle is a part of the transport system in vascular plants. The companion cells run adjacent to sieve-tube members and are connected by a number of channels called ‘plasmodesmata’. On the outside. Key Concepts: Terms in this set (15) Xylem. Sieve tubes are columns of sieve-tube cells with perforations on the lateral wall through which the food substances travel. Phloem is responsible for transporting food produced from photosynthesis from leaves to non-photosynthesizing parts of a plant such as roots and stems. Eighty-two% of xylem-delivered N was consumed in leaf growth, the remainder exported in phloem. Please try again. The outer layer of the vein is made of cells called bundle sheath cells (E), and they create a circle around the xylem and the phloem. The companion cell can sometimes also deliver sugars and other substances into the sieve-tube members from neighboring cells. With the exception of lycophytes, veins divide multiple times in a leaf which creates a good spread of veins and makes it easier to collect sugars and deliver water to photosynthesizing parts of the leaf. The vascular tissue, xylem and phloem are found within the veins of the leaf. Vessel elements are shorter and wider than tracheids and are connected together end-on-end. Both are components of vascular tissues in plants that serve the purpose of transporting materials throughout the plant. In the stems of some Asterales dicots, there may be phloem located inwardly from the xylem as well.
