Anatomy of Monocot Root (Monocot Root Cross Section Under Microscope with Diagram) Ø The anatomical features of a monocot root can be studied through a cross section (CS) through the root. The vascular cambium then divides to form secondary xylem on the inside and secondary phloem on the outside. Helps in the storage of food material and in the lateral conduction of water and food. Vascular bundles are open, collateral and conjoint. 100X at 35mm In a sense, they are to plants what veins and arteries are to animals. The vascular bundles are limited in number and have a uniform size. Monocot and dicot roots have very different appearances. Monocot roots do not show much difference in the anatomy from that of the dicot roots. B. Vascular system Vascular tissues are in radial arrangement. Stele: All the tissues present inside endodermis comprise the stele. From the stele outward there are two ground tissue layers, with the endodermis immediately adjacent to the stele followed by the cortex and the exterior epidermal layer (Fig. The veins start from the center midrib going to the edge of the leaf. Dicot Root. Unlike dicot roots, a monocot root has a pith in the stele.It also contains vascular bundles that are composed of both xylem and phloem. Monocot roots have pith in the centre. (Credit: Wikimedia). B. Dicot roots lack a central pith region. They are densely arranged single cell layer. Monocot Root.

The inner portion of the root contains the vascular tissue (xylem and phloem). The terms dicot, monocot … Zea mays. What is the difference between Monocot and Dicot Roots? Anatomy of Monocot Root, Monocot Root Transverse Section Anatomical Details, TS Monocot Root under the Microscope, Record Diagram for Monocot Root, Epidermis, Cortex, Endodermis and Stele of Monocot Roots, Stelar Features of Monocot Roots, Learn more: Lecture Notes on Anatomy of Monocot Roots 2. In dicot stems, it is situated around the ring of vascular bundles in the stele. Polyarch condition Pith well developed Secondary growth absent Diarch to hexarch (2-6 vascular bundles) condition Pith is very small or absent Secondary growth occurs due to the activity of vascular cambium From the anatomical point of view the monocot … No cavity in the vascular bundles 12. When the plant embryo emerges from the seed, the radicle of the embryo begins to grow downward and forms the root system. Some of the cells give rise to root hairs. It is consists of the following parts. The three layers 1. phelloderm 2. cork cambium and 3. cork cells are collectively known as the periderm. The primary phloem lies… Both, Monocot and Dicot roots belong to plants. 1. The last layer of cells on the edge is the epidermis layer. The vascular tissue is arranged in a ring around the pith and are surrounded by the endoderm. Inside the root, the ground tissue may form two regions: the cortex and the pith (Figure \(\PageIndex{2}\)). The radical of the monocots is replaced by the adventitious roots at early stages. Figure 5.5: The dicotyledonous root The mature root is larger in size than the younger root. Endodermis (4). Dicot root vascular bundles. As the root grows, it thickens and may produce lateral roots in the mature region as shown in Figure 5.5. In certain dicots the root of the same plant may show di-, tri-, and tetrarch xylem. Another difference between monocot stem and dicot stem is that monocot stems contain numerous vascular bundles while dicot stems contain 4 to 8 vascular bundles. Root hairs are tubular in outline and lie in contact with soil water. The cortext is found outside of the stele. Located between the vascular bundles and endodermis. Primary structure of monocotyledonous root - Maize root. The root tip can be divided into three zones: a zone of cell division, a zone of elongation, and a zone of maturation and differentiation (Figure \(\PageIndex{1}\)). Using a needle slowly places the coverslip. If you were to cut a root down longitudinally, you would see the various layers inside. Unless otherwise noted, LibreTexts content is licensed by CC BY-NC-SA 3.0. Several mucilaginous canals can also be observed. Cells of the pericycle and procambium (the meristematic tissue between the primary phloem and xylem) begin division, and form a vascular cambium around the primary xylem. A transverse section of a young monocot root, E.g. Made up of two of these three layers, Consists of thin-walled living cells, parenchymatous cells, Loose arrangement of cells with the presence of intercellular spaces, As seen in the dicotyledonous stem, there is no differentiation of cortex, pericycle and the endodermis, Several scattered vascular bundles found in the ground tissue and are closed type, collateral and conjoint, At the periphery, the vascular bundles are more and densely arranged when compared to the center, Large vascular bundles in the center compared to vascular bundles at the periphery, They resemble an oval shape that is girdled by sclerenchymatous bundle sheath, Metaxylem are present at the two lateral arms. Pericycle is the layers of cells which take place among the vascular and endodermis bundles. Modified by Kammy Algiers and Melissa Ha from the following sources. Gently place the coverslip in order to avoid air bubbles. Active 5 years, 1 month ago. Monocot Root Cross Section. For more information contact us at info@libretexts.org or check out our status page at https://status.libretexts.org. B) Vascular bundles. The monocot … It contains more cuticle than dicot roots. But in monocot roots they are circular. The middle part of the stem inside to the endodermis is termed as stele. Only one xylem strand occurs in the slender root of the hydrophyte Trapa natans. To study the transverse section of a dicot stem, a sunflower stem. ... Monocot root endodermis. 3. Stele cross section. Those plants whose seed contains only one cotyledon or embryonic leaf is known as monocotyledon or simply The veins cross and join forming a netted pattern. These are cells that have the cellulose deposits on the edges and are living cells. Monocots. D. Dicot roots do not form branch roots. Smilax Stele showing bundles of Phloem alternating with Xylem Vessel Members.. Smilax root at higher magnification. Monocot stems contain scattered vascular bundles across the stem while dicot stems contain vascular bundles arranged in the form of rings. A stem is the main axis or stalk of a plant and it develops from the plumule of a germinating seed. The main difference between stems of both the plants is due to the arrangement of the vascular bundle. The one on the left is of the corn seedling at an earlier stage. 6.19) shows differentiation into three regions viz. The veins cross and join forming a netted pattern. Arrangement of Vascular Tissues The specimen provided is a section of a dicot stem. Whereas dicot roots have no central pith, monocots have a small pith. The cork cambium produces parenchyma tissues called phelloderm to the inside of the root and the cork on the outside of the root. Root hairs are tubular in outline and lie in contact with soil water. Piliferous Layer or Epiblema. Pericycle (5). The Xylem is Polyarch. Note that there is no pith in a dicot root. Slice it into thin sections. A. Pericycle . The cortex is between the epidermis and the vascular tissue, whereas the pith lies between the vascular tissue and the center of the root. Viewed 299 times 1.
