Peach Blossom Model Five Petals Ovary Stamen Enlarged Flower Structure Biology Experimental Apparatus Teaching Instrument

I. Model Usage

This model is suitable for middle school biology teaching, when teaching the sexual reproduction organs of angiosperms - the flower structure. The model shows the internal microscopic structure of the ovary and anther through cross-sectional views, enabling students to deepen their understanding of the entire process of pollen.

Section 2: Model Structure

1.The model is a magnified view of a blooming peach blossom, placed on a base.

2.Peach blossoms show the peduncle, calyx, corolla, stamens, and pistils.

3.One stamen, showing the stigma, style, and ovary. The ovary is longitudinally sectioned to show the transverse feet cells, polar nuclei, egg cells, rib cells, and the ovular orifice.

4.Stamen25Show the stamen filaments and anthers. One of the anthers is transversely sectioned to show the pollen sacs, the vascular bundle of the separator, and the pollen grains.

Section 3: Model Use and Storage

1.The sub-compartment and petals of the model can be disassembled for demonstration, and after use, they should be inserted and placed securely in their original positions.

2.After using the model, it should be dust-proofed (remove dust and seal with a plastic bag). The storage site for the product should be clean, dry, and well ventilated, and it should be avoided from direct sunlight.
