Product name: Leaf Structure Model Overview This large, detail leaf model is designed for biology and plant science teaching. Made from durable PVC, it provides clear, accurate views of leaf anatomy for classroom demonstrations, lab practice, and handson learning. Key benefits Improves student understanding by transforming microscopic leaf structures into a visible, threedimensional display. Large and sturdy design makes classroom demonstrations easier and visible to groups. Accurate anatomical detail supports curriculum for dicotyledonous plant study in elementary and middle school biology. Features and anatomical details Upper and lower epidermis are shown, including stratum corneum and epidermal cells. Stomata with guard cells are illustrated; some stomata display the subforamenous cavity. Mesophyll is represented with spongy tissue that shows larger intercellular spaces. Leaf surface includes stalks and sponge tissue profiles with visible nucleus and chlorophyll in some cells. Vein system displays main veins, lateral veins, and irregular veins. Cross section of the main vein reveals the vascular bundle structure, showing xylem, phloem, and leaf formation layer, plus surrounding thinwalled tissue. Side sections demonstrate the relationship between main and lateral veins through multiple sectional views. Sections include partial crosssections and local vertical and horizontal sections modeled on dicot broad bean leaves. Specifications Material: PVC Dimensions: length 450 mm, height 150 mm Main leaf vein height: 200 mm Intended use: biology teaching, plant teaching, visual aid Function and applicability Designed for teaching dicotyledonous plant anatomy in elementary and middle school biology. Helps students visualize internal leaf structures that are difficult to see under a microscope. Suitable for classroom demonstrations, lab stations, teacher training, and museum or exhibit displays. Use scenarios Classroom demonstration: A teacher uses the model during a lesson on leaf anatomy to point out epidermis, stomata, mesophyll, and vascular bundles while students follow along on worksheets. Lab or practical session: Students compare the model to microscope slides of dicot leaves to link macroscopic structures with microscopic detail. Curriculum enrichment or exhibit: The model is placed on a demonstration table in a science fair or museum display to explain how veins, xylem, and phloem function in leaves. Why choose this model Realistic, simulation representation of leaf organs and textures aids clear explanation and retention. Robust PVC construction supports repeated classroom use. Large format and detailed sectional views make it easy to teach and for students to observe key structures. Note For classroom use, combine the model with microscope observations and diagrams to reinforce learning outcomes.
