一、教材分析本节课是七年级生物教材第三单元“生物圈中的绿色植物”的第二章“被子植物的一生”中的第三节。本章以被子植物为例讲述绿色植物的生命周期,按照被子植物生长发育的顺序,依次讲述了“种子的萌发”“植株的生长”“开花和结果”。本章内容要突出植物体自身结构与功能的关系,还要突出植物与环境的关系。学生在前面通过探究实验、调查等活动已经学习了《种子的萌发》和《植株的生长》这两节课的内容,在学习中亲身体验了绿色植物从萌发到生
First, the textbook analysis This lesson is the third unit of the seventh grade biological teaching materials “green plants in the biosphere ” chapter second “the third chapter of the life of angiosperms ”. This chapter takes the angiosperms as an example to describe the life cycle of the green plants. According to the order of growth and development of the angiosperms, we describe the germination of the plants, the growth of the plants, the flowering and the fruiting of the plants. The content of this chapter should highlight the relationship between plant structure and function, and also highlight the relationship between plant and environment. Students in the past through research, investigation and other activities have been studying the “seed germination” and “plant growth” the contents of these two lessons in the learning experience of green plants from germination to birth
