论文部分内容阅读
绿色植物的系列实验教学,由于实验内容较多、实验材料烦琐、实验季节不适合等问题,如果按照教材要求,会出现个别实验完不成或者实验效果不理想等问题,如,观察花的结构、观察叶片的结构、光合作用利用二氧化碳作原料、光合作用产生氧气等。我利用培养学生扦插盆栽的银边天竺葵做实验材料用于该部分的实
The series of experimental teaching of green plants has many problems, such as the large number of experiments, the cumbersomeness of experimental materials, and unsuitable experimental seasons. If the teaching materials are required, problems such as failure of individual experiments or unsatisfactory experimental results may occur, such as the structure of the observed flowers. Observation of the structure of the leaves, photosynthesis using carbon dioxide as a raw material, and photosynthesis to produce oxygen. I use the silver-rimmed geranium cultivated by students to be used as experimental material for this part.
