渗透作用是植物细胞在形成液泡后主要的吸水方式。笔者在有些书刊上看到,选用肠衣、猪膀胱,玻璃纸等作为简单渗透计上的半透膜材料,来演示植物细胞渗透作用的吸水现象。虽然演示中出现了所述的细胞渗透吸水现象,但笔者认为演示植物细胞的渗透作用吸水现象选择上述材料作半透膜是值得商榷的。首先,所介绍的半透膜材料与其所述内容不相符合,造成选择的实验材料与叙述的主体不统一。讲的是植物生理的内容,但选择的是动物体的材料。谈的是植物生活状态的功能,
Osmosis is the main method of water absorption after the plant cells form a vacuole. The author saw in some books and magazines the use of casings, porcine bladder, and cellophane as semipermeable membrane materials on simple osmometers to demonstrate the phenomenon of water absorption in plant cells. Although the phenomenon of cell permeation and water uptake was observed in the demonstration, I believe it is questionable to use the above materials as semipermeable membranes to demonstrate the permeation of plant cells. First, the described semi-permeable membrane material does not correspond to the content described, resulting in the inconsistency between the selected experimental material and the narrative subject. It is the content of plant physiology, but the material of animal body is selected. Talking about the function of plant life,
