In the Monocot Root, Xylem and phloem are numerous in number. Email This BlogThis! 1. The leaf structure, the stem structure and the root structure of monocots plants and dicot plants possess many differences. A leaf with a pinnated pattern (like a feather) has a central vein running down the middle of the leaf with other veins branching off to either side of it. 9. Palisade parenchyma cells occur below the upper epidermis in the dicot root. Origin of Lateral roots : Lateral roots arise endogenously i.e., form the cells inside the endodermis. Anatomy of a Dicot and Monocot Leaves. (i) Palisade parenchyma : These are elongated columnar cells without intercellular spaces. 3. Dicot stem Those plants whose seed contains two cotyledon or embryonic leaf is known as dicotyledon or simply dicot. Difference Between Monocot and Dicot Stem. We will discuss each of them in the following. Read on to explore how monocot and dicot stems vary from each other. 7 leaf dicot The image shows palisade and spongy parenchyma, which are present in dicots. Monocot stem does not undergo secondary thickening while dicot stem undergoes secondary thickening. 11. 10. Monocotyledons and Dicotyledons. It bears unicellular epidermal root hairs with less cutin and more cuticles. 6. 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 Differences between Dicot and Monocot stem. Monocot root has fibrous root-like formation and is present in monocot plants. Phloem is composed of sieve tubes, companion cells and phloem parenchyma. 1. Mesophyll contains chlorophyll. ... Mesophyll is not differentiated into palisade and spongy parenchyma. The mesophyll layer is not differentiated into palisade and spongy parenchyma. Thus a continuous ring of cambium is formed. It bears unicellular epidermal root hairs with less cutin and more cuticles. The dermal tissue system consists of an upper epidermis and lower epidermis. These have chloroplast in them and are generally arranged in two layers. Activity of the cambial ring. anatomy of dicot and monocot leaf ... MESOPHYLL • Tissues between upper and lower epidermis • It posses chloroplast –photosynthesis • Two type- palisade parenchyma, spongy parenchyma 6. 4. In monocot roots, passage cells are absent in endodermis. A monocot root shows 5 distinct regions. Moreover, the mesophyll cells are not differentiated as palisade and spongy parenchyma in a monocot leaf. Dicot leaves have large intercellular spaces in them. The mesophyll is made up of two kinds of tissues, one spongy parenchyma, and the other one is palisade parenchyma. Scope of biology. Leaves - 5 Monocot Leaf Mesophyll • Monocots usually do not have a distinctive palisade and spongy mesophyll. There is no secondary growth in monocot roots. 12. Comparison Chart; Definition; Diagram; Anatomy References Monocot Root . In monocot, stem cambium is present in between xylem and phloem. True Figure 2: The image above shows a cross section of the stem of a dicot plant (left) and monocot (right). Vascular bundles are open. While, monocot root contains xylem and phloem in another manner, forming a circle. Differentiate the following characters of dicot stem and monocot stem. In monocot leaf, mesophyll tissue is not differentiated into palisade parenchyma and spongy parenchyma as in the case of a dicot leaf. Difference # Monocot Root: 1. Pith is either absent or very small. Leaves are very important vegetative organs. The cambial ring becomes active and begins to cut off new cells, both towards the inner and the outer sides. 11. But in monocot leaves palisade parenchyma is absent and only spongy parenchyma present. 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). The cortex … This is the main reason behind dark green colour at upper side of a dicot leaf. The cuticle is present uniformly on the outer and inner surface. The anatomy of the monocot root is similar to the dicot root in many respects (Figure). Legumes (like peanuts, beans, lentils), lettuce, mint, tomato, and the like are typical examples of dicots. On the other hand, these cells are present in the endodermis of dicot … Secondary growth takes place with the help of vascular cambium and cork cambium. 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. i.e. phloem parenchyma is absent. Whereas in Dicot Root, Xylem and phloem are limited in numbers. Comparatively, thick cuticle is present on the upper epidermis. Protoxylem lacuna is absent. Monocots have parallel veins with a general mesophyll of loosely packed parenchyma cells on both sides of the veins extending to the epidermis layers. epdermis; medullary rays; vascular bundles; Previous.
