Vascular Plants. Together, xylem and phloem tissues form the vascular system of plants. The tissues of a plant are organized to form three types of tissue systems: the dermal tissue system, the ground tissue system, and the vascular tissue system. The vascular cylinder of a stem or root is called the stele . Xylem and phloem in stems. Pollen: Pollen with three furrows or pores. The types of vascular tissue used for donation are the saphenous veins and femoral vessels from the lower extremities and the aortoiliac artery from the abdomen. How does donated vascular tissue benefit a recipient? There are two different types of vascular tissues, called xylem and phloem. Presence or absence of wood Vascular Tissue System. In eudicots, vascular bundles are arranged in a ring within the stem. Vascular tissue includes xylem & phloem and helps with water and food transport. Stem and vascular system: Bundles of vascular tissue arranged in a ring. Vascular tissue is an example of a complex tissue, and is made of two specialized conducting tissues: xylem and phloem. The vascular system is divided into a cortex and stele. The vascular tissues are specialized to transport food, water and minerals. Pollen with a single furrow or pore. Xylem and phloem travel entire length of stems in discrete threads called ‘vascular bundles’. Type # 4. Vascular tissue also provides structural support to leaves. Vascular tissue is a complex conducting tissue, formed of more than one cell type, found in vascular plants.The primary components of vascular tissue are the xylem and phloem.These two tissues transport fluid and nutrients internally. The xylem and phloem are kept together in vascular bundles running throughout the ground tissue. They consist of long, narrow cells arranged end-to-end, forming tubes. The two types of vascular tissue, phloem, and xylem are behind the movement of water, minerals, and the products of photosynthesis. Radial Vascular Bundle: A vascular bundle, in which the primary xylem and primary phloem strands are separated from each other by nonvascular tissues and they are situated on alternate radii of an axis, is known as radial vascular bundle or radial bundle. All the tissues of a plant which perform the same general function, regardless of position or continuity in the body, constitute the tissue system. The simplest arrangement of conductive cells shows a pattern of xylem at the center surrounded by phloem. The simplest and apparently most primitive type of stele is the protostele , in which the xylem is in the centre of the stem, surrounded by a narrow band of phloem. Xylem tissue transports water and nutrients from the roots to different parts of the plant, and includes three different cell types: vessel elements and tracheids (both of which conduct water), and xylem parenchyma. The first fossils that show the presence of vascular tissue date to the Silurian period, about 430 million years ago. Moreover, the movement takes place throughout the plant. Vascular tissue also contains parenchyma cells in the vascular cambium, a tissue of cells that can divide to produce new cells for the xylem and phloem. Both are shown in f igure below. Vascular plants are those varieties of plants that have special vascular tissue in them. These vascular tissues are arranged in different patterns in different plant groups and in different parts of the plant. Vascular Tissue: Xylem and Phloem.
