叶绿素溶液在透射光下呈绿色 ,而在反射光下呈红色 ,这种现象叫做荧光现象。在叶绿体中色素的提取和分离的实验中 ,如加上观察荧光现象 ,将会提高学生的学习兴趣。如何才能清楚地观察到荧光现象呢 ?1　色素提取液的处理1 )量取 2 m L色素提取液倒入 1支洁净的试管中。 2 )再向 The chlorophyll solution is green in transmitted light and red in reflected light, a phenomenon known as fluorescence. In the chloroplast pigment extraction and separation experiments, such as coupled with the observation of fluorescence phenomenon, will enhance students’ interest in learning. How to clearly observe the phenomenon of fluorescence? 1 pigment extract treatment 1) Measure 2 m L pigment extract into a clean tube. 2) again
