WebbThe vascular system is comprised of two main types of tissue: the xylem and the phloem. The xylem distributes water and dissolved minerals upward through the plant, from the … WebbPhloem tissue transports organic compounds from the site of photosynthesis to other parts of the plant. The xylem and phloem always lie adjacent to each other in a vascular bundle ( we’ll explore why later ). Each plant organ contains all three tissue types. Koning, Ross E. 1994. Plant Basics.
WebbQUESTION 1 1.1 Explain the terms “fascicular cambium”, “inter-fascicular cambium” and “ vascular cambium ”. Vascular cambium is a an extensive, permanent secondary meristem, one cell thick, conical in form, often described as cylindrical, that begins its development between primary xylem and primary phloem.Fascicular cambium is a vascular cambium … WebbThe main function of phloem is transportation of food materials in different parts of the plant. There are three different types of vascular bundles (Fig. 3.5): (i) Radial Bundles: Xylem and phloem strands are located on alternate radii in radial vascular bundles. These are mainly found in roots. (ii) Conjoint bundles:
