细胞是生物体的基本组成单位。在初中生物学的细胞知识教学中,常常选用比较容易得到的植物体某部分做为实验材料制成装片、徒手切片或压片等,供示范教学或者学生实验观察时使用。通过实验观察,不仅能够使学生加深对植物细胞基本构造的认识,学到制作植物装片的技能,提高使用显微镜进行观察和绘制生物图的技能,而且还能够增强学生对生物学的学习兴趣。因此,上好植物细胞的实验观察课,在初中生物学的教学中是十分重要的。现将适于中学生物学教学中观察植物细胞的方法介绍几个如下:
Cell is the basic unit of organism. In the teaching of cell biology in junior high school biology, some parts of plants which are relatively easy to get are often selected as the experimental materials to be loaded, bare hands or tablet for demonstration teaching or experimental observation by students. Through experimental observation, students can not only deepen their understanding of the basic structure of plant cells, learn the skills of making plant slices, improve their ability to observe and draw biological images by using microscopes, but also enhance students’ interest in biology. Therefore, the experimental observation of good plant cells in the teaching of junior high school biology is very important. Now suitable for teaching high school biology observation of plant cells introduced several are as follows:
