力是一种环境因素,它对生物体的生命活动会造成一定影响.科学家通过力作用的原理,进行了很多卓有成效的实验,并从中得出了一些重要的结论.本文以高中生物学为参照,通过问题呈现的形式,阐释了力在生物学实验中的重要作用.一、验证细胞的结构基础由于细胞中的各种结构的质量存在差异,因此根据其重力的不同,并利用差速离心的方法可将质量不同的细胞结构分开.相关训练在适当条件下,研碎绿色植物叶肉
Force is an environmental factor, which has an impact on the life activities of the organism.Scientists have done a lot of fruitful experiments through the principle of force, and have drawn some important conclusions.According to senior high school biology , Through the form of problem presentation, explained the important role of force in biological experiments.A, verify the structural basis of cells due to the quality of the cells in the various structures are different, so according to their different gravity, and the use of differential centrifugation Method can separate the different quality of cell structure related training under appropriate conditions, ground green leaf mesophyll
