Dynamic meiosis model for biological teaching and using method thereof

[0049] see Figure 1-3 , a dynamic meiosis model for biology teaching, including a demonstration board 1, a plurality of chromosome unit models 2 are arranged on the demonstration board 1, and the same four chromosome unit models 2 can be connected together to form a chromosome, and the demonstration board 1. Both ends of the left and right ends are equipped with a centrosome model shaft 3, which is equivalent to the centrosome of the cell. One end of the centrosome model shaft 3 is connected with a micro motor 4, and two sections of spindle silk model ropes 6 are wound on the centrosome model shaft 3, which are equivalent to Based on the spindle of the cell, the free end of the spindle model rope 6 is fixedly connected with a traction block 5, and the chromosome unit model 2 includes a model color-changing head 201, a power supply trunk 202 and a centromere model connector 203 connected in sequence, and the centromere model Both side walls of the particle model connector 203 awa

[0067] When teaching conditions do not allow, students can use clips instead of chromosome unit model 2 to assemble chromosomes. The shape of the clip is similar to that of chromosomes, and the spring steel wires of the two clips can also form when they are stacked together. Similar to the connection of the centromere, it can be painted on the surface of the clip to overcome the color requirement of the chromosome. The centrosome model axis 3 can be replaced by two hairpins symmetrically placed and glued to the demo board 1. The spindle model rope 6. Use commonly used silk thread instead, and pass through the hole at one end of the hairpin to facilitate limited traction. Red silk thread is preferred, and the color is relatively clear. Simple dynamic meiosis can also be achieved by using the above-mentioned clips and other common parts in life. demo.

[0068] The present invention can realize the independent construction of physical models by teachers or students, adopt dynamic de
