植物细胞吸水方式的教学研究

Teaching Research on the Way of Water-absorbing of Plant Cell

关于植物细胞的吸水方式,传统分类方法为渗透吸水、吸胀吸水和代谢性吸水。而目前在新版教材中出现了新的分类方式:扩散、集流与渗透作用。对新旧两种分类方式之间的内在关联与区别进行总结,以便于加深学生对植物细胞吸水机制的理解,有利于教师全方位的教学。

In traditional classification method, the way of water-absorbing of plant cell is classified as osmosis water-absorbing, imbibition water-absorbing and metabolic water-absorbing. However, the novel classification method in the new version textbook, in which the way of water-absorbing are classified as diffusion, mass flow and osmosis, are introduced. In this paper, internal correlation and difference between the two ways were summarized, so as to make the students better understand the waterabsorbing mechanism of plant cell and contribute to full-dimensional teaching.
