许多基层中学,特别是农村基层中学,由于条件所限,完成高中《生物》教材规定的实验有困难。笔者参阅华东师范大学生物系植物生理教研室主编的《植物生理学实验指导》,对“叶绿体中色素的提取和分离”这一实验加以改进,采用一些易找到的器材药品和一些简便实用的方法,使得在基层中学做这个实验也能取得良好的效果。 Many grass-roots middle schools, especially rural primary-level middle schools, have difficulties in completing the experiments prescribed in the high school “biology” textbooks due to limited conditions. The author refers to the “Plant Physiology Experiment Guide” edited by the Department of Plant Physiology, Department of Biology, East China Normal University, and improves the experiment of “extracting and separating pigments from chloroplasts” using some easily found equipment drugs and some simple and practical methods. In the primary school to do this experiment can also achieve good results.
