在实际生产与生活中,不同情景下“光合速率”的定义指向互有区别,准确辨析净光合速率与真光合速率,是深入理解光合作用原理的必经环节。例1以测定的CO2吸收量与释放量为指标,研究温度对某绿色植物光合作用与呼吸作用的影响,结果如图所示。下列分析正确的是()A.光照相同时间,35℃时光合作用制造的有机物的量与30℃时相等B.光照相同时间,在20℃条件下植物积累的有机物的量最多C.温度高于25℃时,光合作用制造的有机物的
In actual production and life, the definition of “photosynthesis rate ” in different scenarios points to the difference of each other, and the accurate analysis of net photosynthetic rate and true photosynthetic rate is the necessary step to understand the principle of photosynthesis. Example 1 The measured CO2 uptake and release as an indicator to study the temperature of a green plant photosynthesis and respiration, the results shown in Figure. The following analysis is correct () A. Light at the same time, 35 ℃ when the amount of photosynthesis organic matter produced at 30 ℃ equivalent B. Light at the same time, at 20 ℃ under the conditions of plant accumulation of organic matter most C. High temperature At 25 ° C, photosynthesis is made of organic matter
