The Leaf Structure Model is A Visual Teaching Aid Structure of Dicotyledonous Plants Plant Anatomical Leaf Structure Anatomy Model for Biology Teaching Instrument

The model is taken from the dicotyledonous broad bean leaves, and the main veins are used to cross-section some leaves, and locally to make vertical and horizontal sections of different levels.(Length 450m, height 150m, height of main leaf vein 200mm). The model shows the upper and lower epidermis, mesophyll and veins. The epidermis shows the stratum corneum, the epidermal cells and the stomata composed of guard cells: the leaf shows the stalk composition and the sponge tissue; the leaf veins show the main, lateral, and veins. The cross-section of the main vein shows the structure of the tube bundle (showing the xylem, phloem, and leaf formation layers) and the surrounding wall structure. On the side of the model, through the relationship between the small main veins and the lateral veins in various sections; the irregular veins of development are displayed. This model is suitable for secondary school biology teaching, the intuitive teaching aids used to teach the structure of dicotyledons for students to deepen their understanding., Manufacturer: KJMWXOP
