Teaching Model Monocot Stem Cross Section Replica Color A Material PVC Quantity 1 Pc Product overview This teaching model is a PVC replica of a corn stalk transverse section, scaled to show one tenth of the full cross section with the central portion removed to expose internal structures. It is designed as a visual aid for secondary school biology classes to demonstrate the anatomy of monocotyledonous plant stems. Key benefits Clear visualization: Bright, detailed surface texture and simulated ravine features make tissue layers and conduits easy to identify during lessons. Durable material: Molded from PVC for repeated classroom handling and long service life compared to delicate real samples. Anatomically informative: Vshaped conduits, perforated lateral conduits, ringed and threaded terminal conduits, and the size distribution of vascular bundles are represented with fidelity to support accurate observation and explanation. Compact and practical: The 1/10 cross section format with the central portion removed provides clear access to internal structures while keeping the model compact and easy to store. Features Material: PVC replica based on a corn stalk cross section Color: A, as pictured Texture: definition surface texture and simulated ravine design for realistic appearance Vascular detail: Larger perforated conduits positioned laterally, smaller and more numerous vascular bundles toward the edge, larger and fewer bundles on the inner surface Terminal structure: Tip regions show ringed and threaded conduit representations Scale and form: One tenth of the cross section with central part removed to improve visibility of tissues Package contents 1 x Teaching Model Usage scenarios Classroom demonstration: Use the model during lectures to point out and label conduits, vascular bundles, and tissue arrangement in monocot stems. Laboratory practice and group work: Provide students with a durable reference for dissection comparisons and microscopy preparation without relying on fresh specimens. Teacher training and curriculum development: Use the model as a standardized example when preparing lesson plans or demonstrating how to teach stem anatomy. Additional notes Actual product color may vary slightly from images due to display and lighting differences. Manual measurement tolerance: please allow a 1 cm to 2 cm error. This model is intended for educational use as a visual teaching aid for secondary school biology and accurately represents the structural features of monocotyledonous stems for instruction and demonstration.
