高中生物课的内容,主要阐述生命本质的基础知识。第一章“生命的物质基础”部分,难度大,学生不易理解。为了教好这一章,我谨提出几点粗浅的看法: 讲生命的物质基础的时候,首先要指出:地球上的生物,除最低级的之外,都是由细胞构成的;而细胞中的细胞膜、细胞质、细胞核,通称为原生质,它是生命的物质基础。 The content of high school biology courses mainly explains the basic knowledge of the nature of life. The first chapter “The material basis of life” is very difficult and difficult for students to understand. In order to teach this chapter, I would like to make a few superficial observations: When we talk about the material basis of life, we must first point out that the living things on earth, except the lowest class, are made up of cells; The cell membrane, cytoplasm, and cell nucleus, known as protoplasm, are the material basis of life.
