细胞膜是一种半透膜,具有选择渗透性。根据细胞膜这种特性,选用具近似选择透过性能的生物膜状材料或非生物膜状材料用为代选择透过性膜,使其与长颈漏斗组成一个渗透装置,以此来验证细胞的渗透吸水和失水的原理。如何选择实验材料是实验成功的关键,下面介绍几种取材容易且效果良
The cell membrane is a semipermeable membrane with selective permeability. According to the characteristics of the cell membrane, a biological membrane-like material or a non-biological membrane-like material having approximately the permselectivity is selected as the permselective membrane, and a penetrating device is formed with the long-necked funnel to verify the cell’s The principle of penetrating water absorption and dehydration. How to select experimental materials is the key to successful experiments.
