Unformatted text preview: Plant Structures Transport The vascular system in the stem is continuous with that of the roots, providing an easy route for water and nutrients to flow throughout the plant body. The organization of vascular tissues is different for various types of plants--from the scattered vascular bundles (containing both xylem and phloem) of monocots to the more orderly ring formation found in dicots. This difference in the organization of the vascular tissues has implications for the way the plant grows. (For a general discussion of monocots and dicots, see Plant Classification, Monocots and Plant Classification, Dicots.) Monocot Stems In monocots, xylem and phloem are organized in vascular bundles scattered throughout the stem. As the plant grows, monocot stems generate new vascular bundles for the new tissue. Monocot stems in general possess a simpler arrangement than that found in dicots; the main elements of the stem are merely the vascular bundles and the pith (used for nutrient storage) that surrounds...
