【考点归纳】1.影响光合作用的因素(1)光照强度:植物的光合作用强度在一定范围内随着光照强度的增加而增强,但当光照强度达到一定程度时,光合作用的强度不再随着光照强度的增加而增强。①当植物在某一光照强度条件下,进行光合作用所吸收的CO_2与该温度条件下植物进行呼吸作用所释放的CO_2量达到平衡时,这一光照强度就称为光补偿点,这时光合作用强度主要是受光反应产物的限制;
Test sites are summarized as follows: 1. Factors influencing photosynthesis (1) Light intensity: The photosynthesis intensity of a plant increases with increasing light intensity in a certain range, but when the light intensity reaches a certain level, the intensity of photosynthesis no longer As the light intensity increases, it increases. 1 When the plant is under a certain light intensity condition, when the CO 2 absorbed by photosynthesis and the CO 2 amount released by the plant under the temperature condition reach equilibrium, this light intensity is called the light compensation point. The intensity of use is mainly limited by the photoreaction product;
