Simple experiment of leaf photosynthesis
First take two 1000 mL glass beakers, put the same amount of aquatic plants, and then pour the same amount of water into the two beakers. Take two short-handled glass funnels with a diameter slightly smaller than that of the beaker, and put them upside down in the two beakers. [ Beaker 50ml,Beaker Logo,500ml beaker,beaker 100ml ] One of the two beakers is placed in the sun and the other is placed in a dark place. After some time, the water plants in the sun will continue to bubble, but the water plants in the dark are not easy to bubble. [ Beaker 50ml,Beaker Logo,500ml beaker,beaker 100ml ] After a while, you will find that the air in the test tube covered by the water plants under the sun is better than that in the light. There is much more air in the test tube on dark aquatic plants, indicating that plants need sunlight for photosynthesis, and the photosynthetic intensity is different under different light conditions. Finally, cover the mouth of the test tube, take the test tube out gently, and extend a wooden strip with sparks into the test tube. The wooden strip will burn violently and emit a dazzling light, which proves that the photosynthesis of aquatic plants produces oxygen.
