WebbThey are of two types xylem and phloem. Xylem and phloem together make the vascular bundle in plants. 1. Xylem: The cells have thick cell wall and many of them are dead. This tissue helps in the transport of water and dissolved substances throughout the plant. The different components of the xylem include tracheids, vessels, xylem parenchyma ... Webb8 juni 2024 · The phloem is arranged in long, continuous strands called vascular bundles that extend through the roots and stem and reach into the leaves as veins. Vascular bundles also contain the xylem , the tissue that carries water and dissolved minerals from the roots to the shoots.
WebbPhloem differentiation challenges our basic concepts of cells as functional units and our definition of what constitutes a liv-ing cell. Physiology and ontogeny of phloem cells have been extensively studied in the lit-erature ( 4– 6), but we have remained surpris-ingly ignorant about the molecules that drive phloem differentiation.
