What is the vascular cambium normally gives rise to? Xylem: water and mineral transport. The cambium has been variously defined as follows: "The actively dividing layer of cells that lies between, and gives rise to, secondary xylem and phloem (vascular cambium)" (IAWA 1964); "A meristem with products of periclinal divisions commonly contributed in two directions and arranged in radial files. As long as the lateral meristems continue to produce new cells, the stem or root will continue to grow in diameter. In dicot stems, the pericycle strengthens the stem and provides protection for the vascular bundles. The vascular cambium normally gives rise to: Primary phloem . 3. 2. Primary phloem . Formation of the secondary tissues: The cambium ring acts as a meristem which divides. Phelloderm. Answer: From permanent tissues . Furthermore, fascicular cambium gives rise to both primary and secondary vascular components while interfascicular cambium gives rise to the secondary vascular components. The cambium has been variously defined as follows: "The actively dividing layer of cells that lies between, and gives rise to, secondary xylem and phloem (vascular cambium)" (IAWA 1964); "A meristem with products of periclinal divisions commonly contributed in two directions and arranged in radial files. In many vascular plants, secondary growth is the result of the activity of the two lateral meristems, the cork cambium and vascular cambium.Arising from lateral meristems, secondary growth increases the width of the plant root or stem, rather than its length. The vascular meristem, namely the (pro‐)cambium, is a stem‐cell tissue that gives rise to both xylem and phloem. Tangential (face) view of vascular cambium: This is a view of a longitudinal section made just inside the secondary phloem perpendicular to the rays. 11. The vascular cambium is the main growth tissue in the stems and roots of many plants, specifically in dicots such as buttercups and oak trees, gymnosperms such as pine trees, as well as in certain vascular plants.It produces secondary xylem inwards, towards the pith, and secondary phloem outwards, towards the bark.. Answer: Secondary vascular tissues and medullary rays. Note that the xylem (wood) appears to have been produced in bands or rings. Recent studies have revealed that CLAVATA3/Embryo Surrounding Region‐related (CLE) peptides function in establishing the vascular system through interaction with phytohormones. Add your comments. Answers (1) S Sabhrant Ambastha . This type of growth, called also secondary thickening or lateral growth (lateral = to the side), arises from secondary (newly formed) meristems. Anatomically it is termed as phellogen. Root hairs develop from the region of: Elongation . Periderm .
