Monocot Stem Model on Board – Educational Plant Anatomy Teaching Model
The Monocot Stem Model on Board is an educational botanical teaching aid engineered to demonstrate the internal histological organization, cellular differentiation, and vascular architecture of a typical monocotyledonous stem (Zea mays / maize stem). Cast in high relief from unbreakable medical-grade PVC plastic and mounted securely on a finished display board, this model magnifies transverse section (T.S.) microscopic anatomy hundreds of times. It serves as an essential teaching benchmark across secondary school biology classrooms (SSC/HSC), college botany departments, agricultural universities, and plant pathology laboratories throughout Bangladesh.
Understanding plant histology and internal stele differentiation is often challenging for students when relying solely on two-dimensional textbook drawings or prepared glass microscope slides. In monocot stems, the absence of concentric rings and secondary growth creates confusion regarding tissue boundaries. This physical relief model resolves that learning barrier by providing an enlarged wedge sector and cross-sectional view. It clearly illustrates the single-layered epidermis coated with a protective cuticle, the multi-layered sclerenchymatous hypodermis providing mechanical support, and the vast, continuous parenchymatous ground tissue lacking distinct cortex, endodermis, or pith demarcation.
A defining botanical highlight of the model is the detailed representation of scattered (atactostelic) vascular bundles. Each bundle is sculpted in enlarged relief to display its protective sclerenchymatous bundle sheath, phloem elements (sieve tubes and companion cells), and endarch xylem vessels arranged in a distinctive "Y" or "V" formation alongside protoxylem lacunae (water cavities). The board features numbered identification indices paired with an attached laminated reference key card, making it ideal for classroom lectures, group study, and practical viva-voce assessments. Victor Scientific Co. supplies precision-crafted botanical and anatomical models nationwide with guaranteed quality and secure packaging.
✹ Key Features
Magnified Transverse Section (T.S.) Relief
Displays an enlarged wedge sector and cross-sectional plan of a monocot stem, revealing microscopic cellular morphology with clarity.
Scattered Vascular Bundle Architecture
Accurately demonstrates the closed collateral vascular bundles distributed throughout the ground tissue, smaller and denser toward the periphery.
Diagnostic Y-Shaped Xylem & Cavity
Clearly depicts two large pitted metaxylem vessels, smaller annular/spiral protoxylem vessels forming a "Y" shape, and a protoxylem cavity (lacuna).
Distinct Histological Tissue Layers
Differentiates the cuticularized epidermis, mechanical sclerenchyma hypodermis, parenchymatous ground tissue, and sclerenchymatous bundle sheaths.
Durable, Impact-Resistant Construction
Fabricated from high-density, washable PVC plastic or fiberglass mounted on a finished wooden or heavy-duty polymer baseboard that resists tropical humidity.
Vibrant Botanical Color Coding
Finished with non-toxic, fade-resistant pigments that clearly contrast xylem (red/pink), phloem (blue/green), sclerenchyma (yellow), and parenchyma.
Numbered Demonstration Key Card
Features clear numerical callouts stamped beside each anatomical tissue zone corresponding to an included laminated reference chart for practical exams.
Wall-Mountable and Benchtop-Ready
Designed with a balanced footprint suitable for demonstration easels or secure wall hanging in school botany and agricultural science laboratories.
✹ Applications
- Secondary School Certificate (SSC) and Higher Secondary (HSC) biology practical classes and board curriculum exams
