Monocot plants and dicots plants possess many differences both structurally and functionally. The leaf structure, the stem structure and the root structure of monocots plants and dicot plants possess many differences. In monocot roots, passage cells are absent in endodermis. But in monocot leaves palisade parenchyma is absent and only spongy parenchyma present. Monocot root has fibrous root-like formation and is present in monocot plants. Answer: Monocot leaves have veins that are parallel to one another through the length of the leaf and do not branch. Phloem is composed of sieve tubes, companion cells and phloem parenchyma. Monocotyledons and Dicotyledons. The cuticle is present uniformly on the outer and inner surface. There is also secondary growth, more evident in dicots. Differences between Dicot and Monocot stem. Differentiate the following characters of dicot stem and monocot stem. 12. The cambial ring becomes active and begins to cut off new cells, both towards the inner and the outer sides. Note that the dicot seed lacks endosperm, and the monocot does not have the hilum that is present in the dicot seed. Read on to explore how monocot and dicot stems vary from each other. These parts are: Epiblema: This is the single outermost layer of the root made entirely from parenchymatous cells and does not have any intercellular space. The structure of monocot and dicot stem is quite different from each other. Phloem parenchyma is present. Like stem and roots, leaves also have the three tissue system – dermal, ground and vascular.

MESOPHYLL • Tissues between upper and lower epidermis • It posses chloroplast –photosynthesis • Two type- palisade parenchyma, spongy parenchyma 6. It bears unicellular epidermal root hairs with less cutin and more cuticles. Palisade parenchyma cells occur below the upper epidermis in the dicot root. Activity of the cambial ring. The mesophyll layer is not differentiated into palisade and spongy parenchyma. Moreover, the mesophyll cells are not differentiated as palisade and spongy parenchyma in a monocot leaf. Bundle cap is present. 5 seed monocot There is only one cotyledon. 8 leaf monocot The vascular bundles in present in the leaf are evenly spaced. The cortex … It has xylem and phloem in sporadic manners set in a ring-like formation. In monocot leaf, mesophyll tissue is not differentiated into palisade parenchyma and spongy parenchyma as in the case of a dicot leaf. Anatomy of a Dicot and Monocot Leaves. Difference Between Monocot and Dicot Stem. We will discuss each of them in the following. (i) Palisade parenchyma : These are elongated columnar cells without intercellular spaces. Sunflower and Cucurbita are examples of dicot stems. i.e. Anatomy of a dicot and monocot leaves . It is having Vascular bundles are open. 7. The tissue of monocot leaf consists of only one kind of cells that are small oval or spherical or irregular shaped spongy parenchyma cells with chloroplasts and chlorophyll. Palisade lies just inner to the upper epidermis. 4. 9. Dicots leaf have more stomata on their lower surface. We will discuss each of them in the following. Scope of biology. Pericycle is present. Comparison between the Dicot Root and Monocot Root. True Dicot leaves have large intercellular spaces in them. Difference # Monocot Root: 1. These parts are: Epiblema: This is the single outermost layer of the root made entirely from parenchymatous cells and does not have any intercellular space. The anatomy of the monocot root is similar to the dicot root in many respects (Figure). Conjunctive parenchyma forms the cambium. Leaves are very important vegetative organs. They are mainly concerned with photosynthesis and transpiration. Figure 2: The image above shows a cross section of the stem of a dicot plant (left) and monocot (right). It has epidermis, cortex, endodermis, pericycle, vascular bundles and pith. Pith is either absent or very small. Dicot leaves have upper and lower cell layers that are distinct from one another - a palisade layer above (tall, elongate cells) and a spongy mesophyll layer below (isodiametric cells). Like stem and roots, leaves also have the three tissue systems - dermal, ground and vascular. 3. This reticulate venation pattern generally has one of two appearances. In dicot stems, the cells of cambium present between primary xylem and primary phloem is the intrafascicular cambium. A thick cuticle is present on the outer walls of epidermal cells. Leaves - 5 Monocot Leaf Mesophyll • Monocots usually do not have a distinctive palisade and spongy mesophyll. Content: Dicot Vs Monocot Leaf. Palisade parenchyma cells are long column like or pillar like cells present towards the upper surface of a dicot leaf along with spongy parenchyma layers. The plants having seeds with two cotyledons are known as dicots, whereas monocots are the plants whose seeds have a single cotyledon. Monocot and Dicot differ from each other in four structures: leaves, stems, roots and flowers.The difference between dicot and monocot root is, dicot root contains xylem in the middle and phloem surrounding it. Unlike a dicot leaf, where stomata are found in greater numbers in the abaxial epidermis, in a monocot leaf, stomata are present on both surfaces of the epidermis. Above lower epidermis and just below palisade tissue we have the 2nd differentiated layer named spongy tissue. 10. The dermal tissue system consists of an upper epidermis and lower epidermis. Thus a continuous ring of cambium is formed. References monocot stem. 6. Dicot and monocot stems are quite different from each other. 10. Mesophyll contains chlorophyll. The medullary cells adjoining these form intrafascicular cambium. In the Monocot Root, Xylem and phloem are numerous in number. • Palisade parenchyma • Adaxially placed • Elongated cells • Vertically arranged and parallel to each other 7. Click hereto get an answer to your question ️ Bundle sheath extensions in a dicot leaf and in a monocot leaf are - and - respectively. Share to Twitter Share to Facebook Share to Pinterest. Origin of Lateral roots : Lateral roots arise endogenously i.e., form the cells inside the endodermis. Bulliform cells are usually absent. 11. Monocot leaf. The anatomy of a monocot leaf is similar to that of a dicot leaf. Endodermis is distinct as the innermost layer of the cortex. Bulliform cells are present in upper epidermis. Comparison between dicot leaf and monocot leaf Dicot leaf. These have chloroplast in them and are generally arranged in two layers. 6 stem dicot The vascular bundles form a ring around the periphery of the ground tissue. phloem parenchyma is absent.

Learn vocabulary, terms, and more with flashcards, games, and other study tools. Next . Monocot Root Features Of Monocot Roots You Need To Know. Anatomy of Dicot and Monocot Root. They arise from pericycle cells. 6. Monocots have parallel veins with a general mesophyll of loosely packed parenchyma cells on both sides of the veins extending to the epidermis layers. Medullary rays are present. Epiblema or Epidermis– is a single layered, thin walled colorless, polygonal without intercellular spaces, with presence of unicellular root hairs hence referred to as rhizoids or piliferous layer.The root hairs and epidermal cells take part in the absorption of water and minerals from the soil. The monocot leaf is similar to dicot leaf in many ways, however, in monocot leaf, the stomata are present on both upper and lower surface of the epidermis. Cork is not formed. Differentiated cortex, Protoxylem lacuna present, open bundle, bundle sheath, starch sheath, sclerenchymatous hypodermis, scattered bundles, V.Bs. Lysigenous cavity is present in xylem. The region just below upper epidermis have elongated parenchyma cells with chlorophyll filled in and they are called Palisade tissues. A monocot root shows 5 distinct regions. Due to the presence of mesophyll cells, dicot leaves have large intercellular spaces: Monocot leaves have comparatively tighter intracellular space due to the compact arrangement of mesophyll cells: Differentiation of Mesophyll: Differentiated into two parts – upper palisade and lower spongy mesophyll: No such differentiation in a monocot leaf Both, Monocot and Dicot roots belong to plants. Typical dicot stem show following characteristics: Presence of well-defined epidermis with cuticle and multicellular stem hairs. Note how the vascular bundles are scattered in the monocot stem and arranged in a circular pattern in the dicot stem. The mesophyll is made up of two kinds of tissues, one spongy parenchyma, and the other one is palisade parenchyma. Anaerobic respiration produces more ATP than aerobic respiration. Secondary growth takes place with the help of vascular cambium and cork cambium. Anatomy of Dicot and Monocot Root. The dermal tissue system consists of an upper and lower epidermis. 4. Mesophyil: 5. Dicot leaves are not as linear in shape as monocot leaves, and their vascular structures form net-like veins, instead of parallel ones. Comparison Chart; Definition; Diagram; Anatomy 11. Monocot stem does not undergo secondary thickening while dicot stem undergoes secondary thickening. A monocot leaf possesses stomata on both the epidermis layers and they generally have undifferentiated mesophyll. Monocot Root . It is clearly differentiated into palisade and spongy parenchyma.
