Anatomy of Plant Stems and Roots. In monocots, these bundles are widely dispersed throughout the broad cross-section of the stem., with more of the bundles positioned toward the edge of the stem rather than in … (a) Longitudinal section of Iris shoot apex to show the primary thickening meristem (PTM). The transverse section of stem of maize(which is a monocot plant) contains following regions: Epidermis; Hypodermis; Ground tissues; Vascular bundles; Transverse Section of Internal tissues organization of Monocot Stem (Maize) Epidermis is the outermost uniseriate cuticularised layer of parenchyma with stomata. Dicot stem cross section. Stems The vascular bundles of monocots are usually spread throughout the cross-section of the stem. Here are a few clues to help you classify a given plant as a monocot: Flower petals in multiples of 3’s; Leaf veins runs in parallel; Fibrous, branching roots, all connected from the plant stem; Scattered, rather than ringed, vascularization (this is visible in the cross-section of the plant stem) ( b ) Diagram of a young dicot stem cross-section image from your portfolio drop...
