Pollen grains generally possess a single germinal furrow. The mesophyll tissue consists of only one kind of cells which are small oval or spherical or irregular shaped spongy parenchyma cells with chloroplasts and chlorophyll.

A group of flowering plants belonging to the class Lilliopsida (or Monocotyledonae of Angiospermae (angiosperms), characterized by having only one cotyledon in the seed and an endogenous manner of growth The eudicots are the largest group of What Is A Monocot Leaf? Large vascular bundles may show differentiation into Protoxylem and meta-xylem elements. Du kan når som helst endre valgene dine ved å gå til Mine personvernkontroller. Following are the substantial characters to distinguish between the two types of angiosperms: Monocots can be defined as the plants with the seed having only one cotyledon, and the plant is called as monocotyledons, while plants with the seed having two cotyledons are called as dicots, and the plant is called as dicotyledons. The epidermis is the outermost tissue in leaves that is composed of a compact layer of thin-walled barrel-shaped cells. Vascular bundles in monocot leaf can be described conjoint, collateral and closed with endarch xylem. Monocot leaves are the leaves which appear on plants produced from seeds with single cotyledon like Maize, Rice, Orchids, Grass, Wheat, Palm trees, Bananas, magnolia tree etc. The difference between monocots and dicots is that monocots have one cotyledon while dicots have two. The leaf is broader in shape and relatively small. Bundle sheath extension is present in the vascular bundles of both monocot and dicot leaves. There is no secondary growth in monocot roots. Monocots, on the other hand, typically grow a fibrous root system, which is a dense network of roots that grows closer to the soil surface. Epidermis. Monocot and dicot roots contain multiple tissue layers that water moves through before reaching the root's central vascular cylinder. The cuticle on the upper epidermis is thicker than that of lower epidermis. Vascular tissue is an arrangement of multiple cell types in vascular plants which allows for the transport of water, minerals and products of photosynthesis to be transported throughout the plant. The bundle sheath of a monocot leaf may have a single or double layer and formed of colored cells due to presence of chloroplasts. Protoxylem elements are distinguishable as Protoxylem lacuna. Phloem fibres are absent. Over 250,000 species of herbs, shrubs and woody plants are found in angiosperms. The intercellular spaces are relatively small due to compact arrangement of mesophyll cells. The following arrangement of tissues is seen in a cross-section of a dicot leaf. Upper epidermis on its outer surface is covered by a thin cuticle. Dorsiventral is whereby one the plant has two surfaces differing from each other in appearance and structure. Ground tissue is differentiated into stelar and extra-stelar tissues. Reticulate venation is whereby vein are interconnected and form a web-like network. a. Epidermis is single layer in both dicots and monocots. The main difference between monocot and dicot is that monocot contains a single cotyledon in its embryo whereas dicot contains two cotyledons in its embryo. The epidermal cells have sinous lateral walls. In monocot leaf, the mesophyll is not differentiated into palisade parenchyma and spongy parenchyma. 10. Parallel venation is whereby the secondary veins run parallel to each other off a central, perpendicular primary vein. In Monocots the seeds contain one cotyledon. In between the epidermal layers of a monocot leaf there is undifferentiated spongy parenchyma with presence of less number of chloroplasts and chlorophyll and thus both surfaces of the leaf appears to be of same coloration. The dicot stems have trichomes. Xylem consists of metaxylems and Protoxylem vessels. • A typical leaf has a flat blade and, in eudicots, a petiole (stalk) attached to the stem • Leaves of grasses and other monocots are flat … The orientation of a monocot leaf can be described as isobilateral. Vascular bundle presents in both the root. Large vascular bundles do not show differentiation into Protoxylem elements. Dicot leaf large vascular bundles do not show differentiation into Protoxylem elements. Major portions of the ground tissue in both monocot and dicot leaves is parenchymatous.
