关于水生植物的一系列问题--植物学教材质疑(三)

A Series of Questions on Botany of Aquatic Plants Questioning Botany Textbooks(Ⅲ)

许多植物学教材对水生植物的论述有待修正。关于水生植物,特别是浮水植物和沉水植物的定义,有些教材表述不够严谨。同时,在代表植物的选择及其插入的叶解剖图上,一些教材也存在不少问题。此外,水生植物适应综合征是学习的重点,但一些教材出现错误观点。针对上述问题,本文提出了一些修改建议;并且,在沉水植物的教学中,设计了探究式教学方案,独创性地从维持沉水植物低光补偿点的角度引导学生理解沉水植物的适应综合征。

There are some statements about aquatic plants which need to be revised in many botany textbooks.The definition of hydrophytes,especially floating plants and submerged plants,should be more accurate.Meanwhile,multiple problems occur in the selection of various representative plants and diagrams of leaf anatomy.Most importantly,there are mistakes in explanation of the adaptation syndrome of aquatic plants,which is a key point in learning the topic.Herein,suggestions are proposed to address these issues.Additionally,an inquiry-oriented teaching strategy is presented in the botany of submerged plants,along with a unique emphasis on a lower light compensation point of the plants because the reduction of the light compensation point is the key to understanding the syndrome of plant adaptation to submerged life.
