Embodiment Construction

[0023] It is designed and manufactured by using the principle that the two-core lamp tube can walk under the control of the light chaser. Using a PVC plastic tube with a length of 850mm and a diameter of 150mm as the stem, cut 700 mm long from top to bottom at a chord length of 100 mm. Cut horizontally here, and use the lower part as the base; use a 700mm long, 100mm wide, and 3mm thick plastic plate as a longitudinal section; use a 150mm diameter, 5mm thick PVC plate as a cross section to show the xylem and phloem; use red two cores The light strip 2000mm indicates two conduits; the yellow two-core lamp strip 2000mm indicates two screens; AWG copper core wire 5000mm, No. 20 iron wire 1000mm, one green switch and one yellow switch; the names of conduits, screens, xylem and phloem are marked in words ; Two-core light strips and wires are connected with pins as terminal posts.

Abstract

The invention relates to an electric diagram for translocation. The electric diagram for the translocation can display the process of conveying water in a guide tube from bottom to top and the process of conveying organic matter in a sieve tube from top to bottom in the translocation of plants. A red light band represents the guide tube, the flashing of red light represents the process of conveying the water in the guide tube from bottom to top, a yellow light band represents the sieve tube, and the flashing of yellow light represents the process of conveying the organic matter in the sieve tube from top to bottom. The electric diagram is applied to the teaching related to the related content of translocation in biology of a junior high school and enables the teaching of the translocation of the plants to be vivid and interesting, the aim of breaking through key teaching points and difficult teaching points is achieved, and the teaching effect is good.

Description

Technical field [0001] The invention relates to a transduction action electrokinetic diagram, which is a transduction action electrokinetic diagram capable of showing the bottom-up transport process of water in a conduit and the top-down transport process of organic matter in a sieve tube during plant transport. Diagram, the red light strip represents the conduit, the red light flashing indicates the bottom-up transportation process of water in the conduit, the yellow light strip represents the sieve tube, and the yellow light flashing represents the top-down transportation of organic matter in the sieve tube process. Background technique [0002] At present, there is no invention in this respect. Contents of the invention [0003] The present invention provides an electrodynamic diagram of transporting action, which can display the bottom-up transport process of water in the conduit and the top-down transport process of organic matter in the sieve tube in the transport a...
