The structure of monocot and dicot stem is quite different from each other. Monocot leaf. 10. 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. Comparison between dicot leaf and monocot leaf Dicot leaf. 6 stem dicot The vascular bundles form a ring around the periphery of the ground tissue. 8. They are mainly concerned with photosynthesis and transpiration. Phloem is composed of sieve tubes, companion cells and phloem parenchyma. Legumes (like peanuts, beans, lentils), lettuce, mint, tomato, and the like are typical examples of dicots. Conjunctive parenchyma forms the cambium. Mesophyil: 5. 4. Leaves are very important vegetative organs because they are mainly concerned with photosynthesis and transpiration. Dicot and monocot stems are quite different from each other. Oppositely, a dicot leaf possesses stomata only in the lower epidermis, and their mesophyll is clearly differentiated into spongy and palisade parenchyma. (i) Palisade parenchyma : These are elongated columnar cells without intercellular spaces. References Read on to explore how monocot and dicot stems vary from each other. are its examples. It has epidermis, cortex, endodermis, pericycle, vascular bundles and pith. 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. Like stem and roots, leaves also have the three tissue system – dermal, ground and vascular. 1. The cambial ring becomes active and begins to cut off new cells, both towards the inner and the outer sides. Cortex has collenchymatous hypodermis regularly or as discontinuous patches. Cortex is very wide. Vascular bundles are open. Endodermis is distinct as the innermost layer of the cortex. 9. Differences between Dicot and Monocot stem. 8 leaf monocot The vascular bundles in present in the leaf are evenly spaced. monocot stem. Origin of Lateral roots : Lateral roots arise endogenously i.e., form the cells inside the endodermis. The region just below upper epidermis have elongated parenchyma cells with chlorophyll filled in and they are called Palisade tissues. This is the main reason behind dark green colour at upper side of a dicot leaf. 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. Bulliform cells are present in upper epidermis. True Dicot leaves have large intercellular spaces in them. 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). arranged in a ring, closed bundles, phloem parenchyma absent, presence of pith, collenchymatous hypodermis. Whereas in Dicot Root, Xylem and phloem are limited in numbers. Anatomy of a Dicot and Monocot Leaves. Mesophyll contains chlorophyll. Comparatively, thick cuticle is present on the upper epidermis. 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. Bundle cap is present. The mesophyll layer is not differentiated into palisade and spongy parenchyma. Leaves - 5 Monocot Leaf Mesophyll • Monocots usually do not have a distinctive palisade and spongy mesophyll. Moreover, the mesophyll cells are not differentiated as palisade and spongy parenchyma in a monocot leaf. In monocot roots, passage cells are absent in endodermis. These have chloroplast in them and are generally arranged in two layers. A monocot root shows 5 distinct regions. The cuticle is present uniformly on the outer and inner surface. Next .
