Abstract
The upper part and the lower part of a base board 4 of the utility model are provided with parallel hollow tubes (1), and the middle part is provided with separated parallel hollow tubes 1. Each two conductors 2 are arranged in one group, and respectively pass through the hollow tube 1 of the upper part, the hollow tube of the middle part 1, and the hollow tube of the lower part; both ends of the conductor 2 are respectively connected in cross way; each conductor 2 is provided with a chromosome model 3. Each two chromosome models 3 are respectively positioned on both sides of the hollow tube of the middle part. The utility model has the characteristics of simple and compact structure, convenient fabrication, low cost, and convenient operation, the characteristic that the change process of the chromosome in cell division can be effectively demonstrated.
Description
The utility model relates to a kind of demonstrating model, especially can cell division in chromosome change demonstration model.
Pair cell when division in teaching, if any before and after the silk division why in the cell chromosome number can keep constant; Why chromosome number in the meiosis in the cell can reduce by half; The chromosome number problems such as occurring in maiotic which that reduces by half is obtained knowledge to the student and is existed certain obstacle in period, because teaching at present is static demonstration, and as gypsum or plastic pattern, can not be intuitively, the deficiency of the overall process of dynamic demonstration the problems referred to above.
The purpose of this utility model provides a kind of simple in structure, is become specifically static change attitude, the demonstrating model of chromosomal variation overall process in the ocular demonstration cell division by abstract.
The purpose of this utility model is to realize like this, form by hollow tubular, conductor rope, chromosome model, base plate, its base plate upper and lower device has hollow tubular arranged side by side, middle part device that hollow tubular arranged side by side is separately arranged, per two conductor ropes are one group and pass top hollow tubular, middle part hollow tubular, lower hollow pipe respectively, the cross connection respectively of lead two ends, every lead is equipped with chromosome model, and per two chromosome models separately are positioned at hollow tubular both sides, middle part.
When the utility model uses,, make lead chromosome model is installed, can dynamicly demonstrate chromosomal variation in the cell division, can help to understand that chromatid separately forms chromosome in the cell division also along with moving with pulling moving lead two ends; Homologue separately, chromosome number reduces by half and chromosome moves to wait to cell the two poles of the earth and demonstrates overall process, plays an important role at bioconversion medium.
The utility model is simple and compact for structure, makes simply, and cost is low, and is easy to use, can effectively demonstrate in the cell division characteristics such as chromosome change procedure.
Further specify the utility model below in conjunction with accompanying drawing.
Accompanying drawing is the utility model structural representation.
Among the figure: 1-hollow tubular 2-conductor rope 3-chromosome model 4-base plate
As shown in drawings, base plate 4 devices have hollow tubular 1, and the lead 2 that chromosome model 3 is installed passes hollow tubular 1, and lead 2 two ends intersect respectively and are connected.
Claims (1)
1, chromosome change demonstration model in a kind of cell division, by hollow tubular (1), conductor rope (2), chromosome model (3), base plate (4) is formed, it is characterized in that base plate (4) upper and lower device has hollow tubular arranged side by side (1), middle part device has hollow tubular arranged side by side (1) separately, per two leads (2) are one group and pass top hollow tubular (1) respectively, middle part hollow tubular (1), lower hollow pipe (1), the cross connection respectively of lead (2) two ends, every lead (2) is equipped with chromosome model (3), and per two chromosome models (3) separately are positioned at hollow tubular (1) both sides, middle part.
