About This

• This model is made of high-quality synthetic resin or PVC material, which is light, strong and does not deform. The cells of the basic tissue are parenchyma cells, and their arrangement gradually increases from outside to inside.
• The conduit is V-shaped, with the larger ones on both sides being perforated conduits, and the tip being rings and threaded conduits; the vascular bundles are smaller and more numerous on the edge, and larger and less on the inner surface.
• This model is suitable for visual teaching aids used in secondary school biology teaching to teach the structure of monocotyledonous plant stems.
• The model is made from corn stalks, and the model is cut crosswise. Take 1/10 of the cross section and remove the central part.
