The amplification device for photosynthesis and respiration comprises a plant cup which is an open-mouthed cylindrical transparent container, wherein the open-mouthed end is provided with a cup cover; the lower end of the cup wall of the plant cup close to the bottom part is provided with a hole and connected to a straight rubber pipe, and the straight rubber pipe is communicated with the bottom part of a left respiration cup; the upper end of the cup wall of the plant cup close to the top part is provide with a hole and connected to a snakelike rubber pipe, and the snakelike rubber pipe is communicated with the bottom part of a right respiration cup; the inner wall of the respiration cup is in clearance fit and connected with a piston, and the piston and the inner wall of the respiration cup are provided with a sealing element therebetween to seal; the piston is provided with a handle, and the internal part of the piston is hollow and filled with a gas with light density. The amplification device provided by the utility model has the beneficial effects that photosynthesis and respiration processes carried out by the green plants can be observed visually through building a miniature climatic environment and utilizing the characteristic that carbon dioxide and the air are different in density, and the demonstration process is vivid and visualized, thereby deepening the understanding of students for the curriculum.
Description
Technical field
The utility model relates to the biological teaching aid used in junior middle school, and especially a kind of biology Class is photosynthetic and respiration multiplying arrangement with green plants.
Background technology
In the study in junior middle school, due to the characteristics of biological course at the learning phase in junior middle school, the knowledge that classmates are relevant does not also possess fully, the concrete active procedure of understanding relevant biosome is had any problem, the metabolism of biosome is very slow and difficult observation again, allow intuitively classmates understand also very difficult, great majority have to replace understanding by memorize mechanicalling, in the course of time classmates' learning enthusiasm also is subject to certain impact, the demonstration of bioconversion medium also rests on the traditional means such as picture video always, not directly perceived, not lively, student memory is understood not dark.Summary of the invention
In order to overcome the deficiency in background technology, the utility model provide a kind of green plants photosynthetic with the respiration multiplying arrangement, this green plants is photosynthetic builds in a miniature climatope with the respiration multiplying arrangement, observation of plant sunlight is arranged and without sunlight in discharge to absorb gas, amplify intuitively, thereby more directly perceived, lively help student understands content.
the technical solution of the utility model is: this green plants is photosynthetic comprises the plant cup with the respiration multiplying arrangement, the plant cup is a uncovered cylindrical transparent containers, opening end is placed bowl cover, bowl cover is a taper rubber lid, the uncovered diameter of plant cup less than the conical surface major diameter of bowl cover greater than its conical surface minor diameter, the wall of cup lower end of plant cup is by the straight sebific duct of the porose connection in bottom, straight sebific duct is communicated with bottom left breathing cup, the close snakelike sebific duct of the porose connection in top in wall of cup upper end of plant cup, snakelike sebific duct is communicated with bottom right breathing cup, it is a uncovered cylindrical transparent containers that cup is breathed in the left and right, breathing cup inwall and piston clearance is connected, between piston and breathing cup inwall, the seal element sealing is arranged.
In such scheme, handle is arranged on piston, piston 2 inner hollow and be full of the gas of light density.
The beneficial effect that the utlity model has is: by building a miniature climatic environment, utilize the carbon dioxide characteristic different from the density of air, can observe intuitively the process that green plants carries out photosynthetic left and right and breathes the left and right, presentation process is vividly directly perceived, deepens the student to the understanding of course.
Description of drawings:
Accompanying drawing 1 is structural representation of the present utility model.
In figure 1, left breathing cup; 2, piston; 3, handle; 4, seal element; 5, straight sebific duct; 6, the plant cup; 7, bowl cover; 8, snakelike sebific duct; 9, right breathing cup.
Embodiment:
the utility model is described in further detail below in conjunction with accompanying drawing 1: this green plants is photosynthetic comprises plant cup 6 with the respiration multiplying arrangement, plant cup 6 is uncovered cylindrical transparent containers, opening end is placed bowl cover 7, bowl cover 7 is a taper rubber lid, the uncovered diameter of plant cup 6 less than the conical surface major diameter of bowl cover 7 greater than its conical surface minor diameter, the wall of cup lower end of plant cup 6 is by the straight sebific duct 5 of the porose connection in bottom, straight sebific duct 5 is communicated with left breathings glass 1 bottom, the close snakelike sebific duct 8 of the porose connection in top in wall of cup upper end of plant cup 6, snakelike sebific duct 8 is communicated with right breathings glass 9 bottoms, left, right breathing cup (1, 9) be a uncovered cylindrical transparent containers, left breathing cup 1 inwall is connected with piston 2 clearance fit, between piston 2 and left breathing cup inwall, seal element 4 sealings are arranged.
In such scheme, handle 3 is arranged on piston 2, piston 2 inner hollow and be full of the gas of light density.
In the utility model, three receptacle are all air, air pressure is balance, when shining in the sun, absorbing carbon dioxide when carrying out the photosynthesis releasing oxygen, due to carbon dioxide than oxygen than great, the oxygen that discharges can progress into right breathing cup 9(piston and rise), and suck carbon dioxide (piston decline) from left breathing cup 1, just in time opposite when there is no sunlight, the bottom that the carbon dioxide that discharges sinks to plant cup 6 enters the rising of left breathing cup 1(piston), and absorb oxygen (piston decline) from right breathing cup 9.
during actual the use, bowl cover 7 is removed, one basin green plants is placed in the plant cup, simultaneously two of left and right piston 2 is taken off, cover bowl cover 7, and then piston 2 is placed on gently in breathing cup, device is placed on lower a period of time of sunlight, observe the lifting situation of two pistons 2 in left and right, to install night and place without the local of light or cover up with lighttight cloth, observe again the lifting situation of two pistons 2 in left and right morning, thereby understand sunlight for the mechanism of green releasing oxygen absorbing carbon dioxide, when there is no sunlight, green plants absorbs the mechanism of oxygen release of carbon dioxide, can be when experiment finishes, open two of left and right and breathe cup piston 2, put into a candle of lighting, observe candle and enter the variation of breathing the rear flare of cup.
Can also draw scale breathing on cup, record green plants and absorb what and the temperature that discharge gas, sunlight strength to knowledge such as photosynthesis, respiratory impacts.
