高中生物实验中,有多个实验需要将动、植物的组织破坏,教材中都用研钵、石英砂来完成实验的。实验中材料使用量大,而且实验时间长、效果不尽人意。笔者在实验中使用了多功能搅拌机,省时、省物,而且实验效果很好。一、植物组织液高二生物实验一“生物组织中还原糖、脂肪、蛋白质的鉴定”中,大豆、水果的组织液都是采用研钵研磨,为了使研磨的效果好一点,在研钵中加入了少量的石英 In high school biology experiments, there are multiple experiments that need to destroy the tissues of animals and plants. In the teaching materials, mortars and quartz sand are used to complete the experiments. The amount of materials used in the experiment was large, and the experiment time was long and the effect was not satisfactory. The author used a multi-functional mixer in the experiment to save time and material, and the experiment worked well. I. Plant tissue fluids Bibiology Experiment I “Identification of reducing sugars, fats, and proteins in biological tissues.” Soybeans and fruit tissue fluids were ground using a mortar. To make the grinding effect better, a small amount was added to the mortar. Quartz
