光合和呼吸,是植物和外界发生物质和能量交换的主要形式。其中的生物化学变化,比较难学难记,但农广校学习的重点是理论在生产实践中的应用,并不要求学员深钻生理过程。从这点出发去学习,也就不是太困难的。光合和呼吸关系是很密切的。呼吸是植物体物质和能量转化的中心,但呼吸的产物——葡萄糖又是光合产物,它释放的能量也就是经光合作用固定的太阳能,转变为高能物质 ATP 的形式。学员们容易 Photosynthesis and respiration, is the main form of exchange of matter and energy between plants and the outside world. Biochemical changes among them are more difficult to learn. However, the key point of ABC’s study is the application of theory in production practice, and does not require trainees to deeply study physiological processes. Starting from this point to learn, it is not too difficult. Photosynthesis and respiratory relations are very close. Breathing is the center of the plant material and energy conversion, but the product of breathing - glucose is a photosynthetic product, its release of energy is the photosynthesis of solar energy, into the form of high-energy substances ATP. Students are easy
