Vascular bundles are conjoint and collateral in In dicotyledons, the vascular system of the internode commonly appears as a hollow cylinder delimiting an outer and an inner region of ground tissue, the cortex and the pith, respectively. The vascular tissues of dicot leaf are conjoint, collateral and closed. Similarities between Monocot Leaf and Dicot Leaf . The following arrangement of tissues is seen in a cross-section of a dicot leaf. Similarities Between Monocot Stem and Dicot Stem. The bundle sheath of a monocot plant leaf may have a single or double The epidermal cells have sinous lateral walls. The mesophyll usually has two regions the spongy and relatively smaller whereas a monocot plant leaf is slender and long in shape. Generally, dicot leaf is broader in shape and relatively small in size. and formed of colorless cells. If you look inside the seed once it has germinated you will see one tiny little seed leaf. whereas in monocot leaf, both small and large vascular bundles are present. Among them, the family Orchidaceae (orchids) contains more than 20,000 species. The major role of the stomata of monocot and dicot plants is to facilitate the gas exchange. Chloroplasts are present in the mesophyll of both dicot and monocot leaves. interconnected and form a web like network). These two differ in four different structural traits: roots, stems, leaves and flower. both monocot and dicot leaves. Monocotyledons (Liliopsida) are a class of flowering plants, distinguished by the presence of one terminal cotyledon in each seed. Single layered epidermis with thick cuticle 2. The intercellular spaces of a dicot plant leaf are relatively large Monocotyledon seeds possess a well-developed endosperm. A "difference between" reference site. a monocot plant leaf. Dicot and monocot leaves show considerable differences both in their morphological and anatomical characteristics. The bundle sheath of a dicot plant leaf generally has a single layer It is also described as conjoint and collateral because phloem and xylem are present on the same radius whereas xylem bundles are described as endarch because the Protoxylem vessels face towards the upper epidermis. Dicot and monocot stems are quite different from each other. They both possess chloroplasts. Monocots have long, narrow leaves with parallel veins (like grasses) arranging the parts of monocot flowers in threes or multiples of three. The main difference between monocots and dicots is that monocots have only one cotyledon, or embryonic leaf, whereas dicots have two. A thick layer of the cuticle is present in both stems. A monocotyledon (or monocot) is an angiosperm that has only one cotyledon (or seed leaf.) The cells are cubical or barrel in shape and arranged very closely without any intercellular spaces. Dicot leaf can be described as This is a condition whereby the stomata are only present on the lower surface of the leaf. shaped endodermal cells. On the other hand, the upper The hypodermis is formed of collenchyma fibres which are often green in colour. The vascular bundles in dicot leaf are large and generally present in the veins of the leaf. Monocots and Dicots are two subgroups of Angiosperms. Pith: In dicot root pith is less developed or absent. Species: Monocotyledon is a smaller group of flowering plants with 60,000 species of plants. Monocots and Dicots are two main groups of flowering plants. In monocot leaf, large vascular bundles may show The difference between dicot and monocot root is, dicot root contains xylem in the middle and phloem surrounding it. Dicots come with two embryonic leaves. Dicot Stem: The dicot stem has single layered epidermis along with the thick cuticle.

Monocotyledon seeds possess a well-developed endosperm. In this article, learn the difference between and guard cells. On the upper epidermis there is also presence of few large bubble-like cells referred to as motor cell or bulliform cells which are thought to help the leaf bend or fold and thus reducing surface area exposed to sunlight consequently reducing the rate of transpiration. Monocots have long, narrow leaves with parallel veins (like grasses) arranging the parts of monocot flowers in threes or multiples of three.
