在初中《生物》教材的“植物”部分中 ,光合作用的生理实验有三个 :①绿叶在光下制造淀粉 (分组实验 ) ;②光合作用产生氧气 (演示实验 ) ;③光合作用吸收二氧化碳和水 (演示实验 )。这些知识贯穿高中生物教材 ,在整个中学生物知识中占有十分重要的地位。我在近几年的教学工作
In the “plants” section of the “biology” textbook for junior high school students, there are three physiological experiments for photosynthesis: 1 Green leaves produce starch under light (grouping experiments); 2 Photosynthesis produces oxygen (demonstration experiments); 3 Photosynthesis absorbs carbon dioxide and water (demonstration experiment). This knowledge runs through the high school biology textbooks and occupies a very important position in the middle school biology knowledge. My teaching work in recent years
