对于生物与环境的关系,学生在学习植物学时已有一定程度的了解,如种子萌发时需要水分、空气和适当的温度;绿色植物的光合作用需要光、水、二氧化碳及适宜的温度。但每一植物种群的生长状况与哪些条件有关系?有什么样的关系?这都是“生物与环境”一章教学要解决的问题。本章可有两种教法:一种教法是在教室里教师讲,学生听。按这种教法,教师辛辛苦苦讲完了全部内容,学生连影响生物生长发育的生物与非生物因素有哪些,还没清楚,这不
Students have a certain degree of understanding of the relationship between biology and environment when studying botany, such as the need for moisture, air and proper temperature when seeds germinate. The photosynthesis of green plants requires light, water, carbon dioxide and suitable temperature. However, what is the relationship between the growth status of each plant population and what conditions are there? All these are problems to be solved in the teaching of “Biology and Environment”. There are two ways in this chapter: one is teaching in the classroom, listening to students. According to this teaching method, the teacher worked hard to finish all the contents, and even the biological and non-biological factors that affect the growth and development of the students, what is not clear, which is not
