Technical Field
The utility model provides a plant cell division process demonstrator used in the field of teaching appliances.
Background
Cells are the basic units that constitute the structural functions of an organism, and cell division is the process by which a parent cell divides into two daughter cells. The division of the cell on the plant is directional, the content is relatively abstract, the division is not easy to understand generally, if the demonstrator is used for presenting the whole process of the plant cell division, the division process can be easily understood, and the dynamic process of the plant cell division can be vividly and vividly presented, so that the learning interest is improved, and the deep understanding and mastering of the cell division process are facilitated.
Disclosure of Invention
In order to utilize the demonstration ware demonstration plant cell division process, the utility model provides a plant cell division process demonstration ware. The demonstrator solves the technical problem of demonstration of the cell division process through a demonstration model.
The utility model provides a scheme that technical problem adopted is:
the two sides of the base box body are respectively provided with an upright post, the upper end of the upright post is provided with a simulated cell body, a simulated cell splitting frame is arranged between the two simulated cells, the inside of the simulated cell body is a simulated cell splitting frame which is equivalent to a spindle body, chromosome guide rods are arranged between the simulated cells on the two sides of the simulated cell splitting frame through a cross strut and an upright strut, the centers of the four chromosome guide rods are sleeved with simulated chromosomes, the two sides of the simulated chromosomes are respectively connected with a driving wheel arranged in the simulated cells through chromosome guy wires and are connected with a guy wire wheel arranged on a positive and negative rotation motor through a base guide wheel and a middle guide wheel arranged on the base box body, and the positive and negative rotation motor is connected.
The simulated chromosome is divided into two halves, and an elastic silk is connected between the two halves.
The positive effects are as follows: the utility model discloses through the demonstration of participating in the cell division process, make the demonstration process that the student mastered the cell division demonstration ware better conscientiously, cultivate the hands-on ability simultaneously, improve student's analysis and sum up ability and experiment and explore the ability, and then improve student's biological literacy. The cell division demonstrator is suitable for being used as a teaching appliance of the cell division demonstrator.

Detailed Description
The two sides of a base box body 1 are respectively provided with an upright post 2, the upper end of the upright post is provided with a simulated division cell 3, a simulated cell body 4 is arranged between the two simulated division cells, a simulated cell division frame is arranged inside the simulated cell body and is equivalent to a spindle body, chromosome guide rods 14 are arranged between the simulated division cells on the two sides of the simulated cell division frame through a cross strut 5 and an upright strut 6, the centers of the four chromosome guide rods are sleeved with simulated chromosomes 15, the two sides of the simulated chromosomes are respectively connected with a driving wheel 7 arranged in the simulated division cells through chromosome pull wires 8 and are connected with a pull wire wheel 11 arranged on a positive and negative rotation motor 12 through a base guide wheel 9 and a middle guide wheel 10 arranged on the base box body, and the positive and negative rotation motor is electrically connected with a positive and.
The simulated chromosome is divided into two halves, and an elastic silk 15.1 is connected between the two halves.
The mock cell body is a cell wall.
The battery is arranged in the base box, and a battery power line is connected with the positive and negative rotation motor circuit through the positive and negative switch.
Demonstration of cell division process:
before demonstration, the simulated chromosome is in the middle position of the simulated cell division frame and is in an undivided state.
The positive and negative switches are pressed, the positive and negative rotating motors are operated to drive the wire pulling wheel to rotate, the wire pulling wheel is pulled with two ends of the simulated chromosome through the transmission of the middle guide wheel and the base guide wheel, the two sides of the simulated chromosome are separated by silk striking, two groups of simulated chromosomes are formed, the two groups of simulated chromosomes move to two sides through the chromosome wire pulling and are pulled into the simulated mitotic cells, and the mitotic process of the cells is reflected.
If the demonstration is continued, the positive and negative switch is pressed again to enable the positive and negative rotating motor to move reversely, so that the chromosomes of the dividing cells are restored to the initial state.
In summary, the demonstration of the process of cell division using the present demonstrator, of course, also known cytological principles need to be mastered.
The method is characterized in that:
through the demonstration of participating in the cell division process, the students can better master the cell division demonstrator and can be applied to high school biology learning. The research enthusiasm is stimulated, the practical ability is cultured, the thinking is developed, the analysis and induction ability and the experimental exploration ability of students are improved, and the biological literacy of the students is further improved. The content knowledge palm is obviously improved, the traditional teaching mode is broken through, and the effect of understanding by students is better than that of teaching knowledge by teachers in class originally.
The demonstration process of the demonstrator can be understood through demonstration of the demonstrator and by combining cytology knowledge learned by students.
