《普通高中生物课程标准(实验)》关于“能量之源——光与光合作用”中“光合作用的原理和应用”的具体内容要求是：“说明光合作用以及对它的认识过程，研究影响光合作用速率的环境因素”。某教材该节教学内容首先交代了“光合作用”的定义，之后通过介绍“光合作用的探究过程”中科学家的探索思路。奠定对光合作用具体过程的知识和方法基础。紧接着详细说明了“．光合作用的过程”中物质的变化和能量的转化，然后联系农业生产实际，总结“光合作用的意义”和“光合作用原理的应用”。通过“探究环境因素对光合作用的强度的影响”的探究实验，深化对光合作用的理解和应用。最后与光合作用对比，简述“化能合成作用”，完善自养生物的营养类型。
依据上述内容。确定本节课教学目标及课时安排。

An Essential Scientific Process
All life on the earth depends upon green plants. Using sunlight, theplants produce their own food. Then animals feed upon the plants. They take inthe nutrients the plants have made sted. But that’s not all.Sunlight also helps a plant produce oxygen. Some of the oxygen is used by theplant, but a plant usually produces me oxygen than it uses. The excess oxygenis necessary f animals other ganisms to live.
The process of changing light into food oxygen is calledphotosynthesis. Besides light energy from the sun, plants also use water carbon dioxide. The water gets to the plant through its roots. The carbondioxide enters the leaves through tiny openings called stomata. The carbondioxide travels to chloplasts, special cells in the bodies of green plants.This is photosynthesis takes place. Chloplasts contain the chlophyllsthat give plants their green col. The chlophylls are the molecules thattrap light energy. The trapped light energy changes water carbon dioxide toproduce oxygen a simple sugar called glucose.
Carbon dioxide oxygen move into out of the stomata. Watervap also moves out of the stomata. Me than 90 percent of water a planttakes in through its roots escapes through the stomata. During the daytime, thestomata of most plants are open. This allows carbon dioxide to enter the leavesf photosynthesis. As night falls, carbon dioxide is not needed. The stomataof most plants close. Water loss stops.
If photosynthesis ceased, there would be little food other ganicmatter on the earth. Most ganisms would disappear. The earth’s atmospherewould no longer contain oxygen. Photosynthesis is essential f life on ourplanet.
