笔者阐述了“细胞大小与物质运输的关系”这一实验中使用的琼脂块的具体制备过程,以及琼脂回收再利用的方法,并对实验中的操作难点进行了说明,提出了该实验步骤的改进方法,提高了实验效果,体现了生物实验中的绿色环保理念。一、琼脂块的制备在“细胞大小与物质运输的关系”中要用到琼脂块,教材上未明确说明琼脂块的制备方法,为此,笔者将琼脂块的制备方法阐述如下:
The author elaborated the concrete process of agar block used in this experiment and the method of agar recovery and reuse, and explained the operation difficulties in the experiment, and proposed the experiment Steps to improve the method to improve the experimental results, reflecting the concept of green experiments in biological experiments. First, the preparation of agar block In the “cell size and material transport ” to use agar block, the teaching material is not clear on the preparation of agar block, for which, I will agar block preparation method is described as follows:
