“光合作用”一节是高中生物学的教学重点，也是进一步学习植物生长发育、生态系统、环境保护等内容的基础。其中特别是光反应和暗反应中物质和能量的复杂转变过程，则是这一课的重点与难点，它不仅牵涉到物理、化学、植物学和植物生理学等多门学科的知识，而且还受到实验条件 The “Photosynthesis” section is a high school biology teaching focus, but also to further study the plant growth and development, ecosystems, environmental protection and other content. Among them, the complex and transitional process of matter and energy in photoreactions and dark reactions is the focus and difficulty of this course. It not only involves the knowledge of many subjects such as physics, chemistry, botany and plant physiology, but also Experimental conditions
